The Trans-Canada Highway (French: Route Transcanadienne; abbreviated as the TCH or T-Can)[3] is a transcontinental federal–provincial highway system that travels through all ten provinces of Canada, from the Pacific Ocean on the west coast to the Atlantic Ocean on the east coast. The main route spans 7,476km (4,645mi) across the country, one of the longest routes of its type in the world.[4] The highway system is recognizable by its distinctive white-on-green maple leaf route markers, although there are small variations in the markers in some provinces.
While by definition the Trans-Canada Highway is a highway system that has several parallel routes throughout most of the country, the term "Trans-Canada Highway" often refers to the main route that consists of Highway1 (British Columbia, Alberta, Saskatchewan, and Manitoba), Highways17 and 417 (Ontario), Autoroutes 40, 20 and 85 (Quebec), Highway2 (New Brunswick), Highways104 and 105 (Nova Scotia) and Highway1 (Newfoundland). This main route starts in Victoria and ends in St. John's, passes through nine of the ten provinces and connects most of the country's major cities, including Vancouver, Calgary, Winnipeg, Ottawa, Montreal, Quebec City and Fredericton. One of the main route's eight other parallel routes connects to the tenth province, Prince Edward Island.
While the other parallel routes in the system are also technically part of the Trans-Canada Highway, they are usually considered either secondary routes or different highways all together. For example, Highway16 throughout Western Canada is part of the Trans-Canada Highway system, but is almost exclusively referred to as the Yellowhead Highway and is often recognized as its own highway under that name. In comparison, Highway1 in Western Canada is always referred to as the Trans-Canada Highway, and has a significantly higher traffic volume with a route passing through more major cities than the less important Highway16 (Yellowhead) TCH route. Therefore Highway1 is usually considered to be part of the main Trans-Canada Highway route, while Highway16 is not, although it may be considered a second mainline corridor as it serves a more northerly belt of major cities.
Examples of marker variations between provinces: British Columbia, Quebec, and Newfoundland and Labrador
Canada's National Highway System is not under federal jurisdiction or coordination, as highway construction and maintenance are entirely under the jurisdiction of the individual provinces, who also handle route numbering on the Trans-Canada Highway. The Western provinces have voluntarily coordinated their highway numbers so that the main Trans-Canada route is designated Highway1 and the Yellowhead route is designated Highway16 throughout. Prince Edward Island and Newfoundland and Labrador also designate Highway1 as their section of the TCH, while New Brunswick utilizes Highway2 (a separate important highway—albeit non-TCH—is Highway1 in that province). East of Manitoba, the highway numbers change at each provincial boundary, or within a province (especially in Ontario and Quebec) as the TCH piggybacks along separate provincial highways (which often continue as non-TCH routes outside the designated sections) en route. In addition, Ontario and Quebec use standard provincial highway shields to number the highway within their boundaries, but post numberless Trans-Canada Highway shields alongside them to identify it. As the Trans-Canada route was composed of sections from pre-existing provincial highways, it is unlikely that the Trans-Canada Highway will ever have a uniform designation across the whole country.
Highway design and standards
Unlike the Interstate Highway System in the United States, the Trans-Canada Highway system has no national construction standard, and was originally built mostly as a two-lane highway with few multi-lane freeway or expressway sections, similar to the older United States Numbered Highway System. As a result, highway construction standards vary considerably among provinces and cities. In much of British Columbia, Ontario, and throughout Prince Edward Island and Newfoundland and Labrador, the Trans-Canada Highway system is still in its original two-lane state. On the other hand, New Brunswick is the only province to have its whole length of the main Trans-Canada Highway route upgraded to a four-lane freeway standard. In Quebec, most sections of the TCH network overlap with the province's Autoroute freeway system, resulting in the Trans-Canada Highway following freeways throughout most of Quebec as well. Alberta and Saskatchewan also have upgraded large portions of their Trans-Canada Highway network, with their entire length of Highway1 and even most of Highway16 upgraded to a four-lane divided highway, albeit with at-grade intersections in most areas. British Columbia is actively working on converting its section of Highway1 east of Kamloops to a four-lane, non-freeway route. Currently, over half of the mainline Trans-Canada Highway is still in its original two-lane state, with no bypasses, interchanges and few passing opportunities. Only about 15 per cent of the mainline route is upgraded to freeway standards similar to those of the Interstate Highway system.
Like former U.S. Route 66, the many non-expressway sections of the Trans-Canada Highway often form the Main streets of communities, with a wide variety of small businesses and traveller services having signage and buildings directly adjacent to the Trans-Canada Highway, and in some cases even driveways directly off the highway. These tourist- and traveller-oriented business districts tend to generate significant revenue and employment for their respective communities, especially in the summer. However, the heavy commercial development on many sections of the highway can also cause traffic problems, due to the lower speed limits, signal lights and crosswalks required to service them.
Freeway portions are rare compared to the length of the Trans-Canada Highway network. They exist over significant distances in British Columbia's Lower Mainland, between Calgary and Banff, in Ontario and in Quebec where the network overlaps portions of those provinces' 400-series highways and Autoroutes, across all of New Brunswick, and in the western part of Nova Scotia. Outside of these freeway areas, the highway ranges from being a high-speed four-lane rural expressway to a narrow, winding, substandard two-lane route, subject to dangerous driving conditions and frequent closures. In many cities, the main highway routes are forced onto busy arterial streets with many traffic lights. Examples of this are where the route passes through Victoria, Nanaimo, Kamloops, and Salmon Arm, Calgary and Winnipeg. A TCH-designated expressway bypass exists around Winnipeg, although Highway1 proper still passes through the city on surface streets. In Calgary, the Stoney Trail provides a freeway bypass around its heavily congested urban arterial section of Trans-Canada Highway, although Stoney Trail itself is not considered part of the TCH system.
The Trans-Canada Highway is not always the preferred route between two cities, or even across the country. For example, the vast majority of traffic travelling between Hope, British Columbia, and Kamloops takes the Coquihalla Highway via Merritt, a freeway, rather than the semi-parallel, but longer, Trans-Canada Highway route via Cache Creek, which remains a windy two-lane road. Another example is that much long-distance traffic between Western and Eastern Canada will drive south into the United States and use the Interstate Highway System, rather than the long, windy, two-lane Trans-Canada Highway through Northern Ontario, which is slow and subject to frequent closures.
The main Trans-Canada Highway is uniformly designated as Highway1 across the four western provinces. The British Columbia section of Highway1 is 1,045km (649mi) long, beginning in Victoria at the intersection of Douglas Street and Dallas Road (where the "Mile0" plaque stands), and ending on the Alberta border at Kicking Horse Pass. The highway starts by passing northward along the east coast of Vancouver Island for 99km (62mi) to Nanaimo along a mostly four-lane, heavily-signalized highway. After passing through downtown Nanaimo on a small arterial road it enters the Departure Bay Terminal and crosses the Strait of Georgia to Horseshoe Bay via BC Ferries. From there, it travels through Metro Vancouver on a four- to eight-lane freeway before leaving the city and continuing as a four-lane freeway eastward up the Fraser Valley to Hope. There the Trans-Canada Highway exits the freeway and turns north for 186km (116mi) through Fraser Canyon and Thompson Canyon toward Cache Creek, mostly as a two-lane rural highway with only occasional traffic lights. Highway5 provides a more direct freeway route between Hope and Kamloops, leaving the Fraser Canyon route (the official TCH route) as more of a scenic option or for local traffic. Approaching Kamloops, Highway1 re-enters a short freeway alignment (briefly concurrent with Highways 5 and 97), before passing through Kamloops itself as a four-lane signalized highway. From Kamloops, the highway continues east as a mostly two-lane rural highway through the Interior of British Columbia, with occasional passing lanes. It widens to a signalized four-lane arterial road for short stretches in Salmon Arm, Revelstoke and Golden, but has no signal lights on it for most of its length. The highway crosses two high passes along its route: Rogers Pass in Glacier National Park, and Kicking Horse Pass in Yoho National Park. At Kicking Horse Pass, the highest point on the whole Trans-Canada Highway system is reached, at 1,627m (5,338ft).
Highway1 in British Columbia has four freeway segments. These are in Victoria, through the Lower Mainland, and west and east of Kamloops (the second and third of those sections are connected by the Coquihalla Highway, which is a freeway route that is the preferred route for through traffic). The rest of the highway is either a heavily-signalized four-lane route or a winding two-lane route with passing lanes and occasional four-lane sections. The freeway section of Highway1 through Vancouver is notorious for its traffic, and is one of the most congested roads in Canada. The Highway1 approach from North Vancouver to the Ironworkers Crossing is known to regularly form traffic jams that are an hour long during rush hour. Further east, another section of Highway1 freeway between Langley and Abbotsford is locally known for being congested all day long. Both of these bottlenecks are caused by a lack of effective alternative routes, since Highway1 is the only major east–west route through the city and the outdated four-lane freeway is used beyond its design capacity. Smaller traffic delays are known to exist on the highway during rush hour in Kamloops and Victoria, and during long weekends at the Revelstoke and Kicking Horse Canyon bottlenecks. In addition to the traffic problems, Highway1 over Rogers Pass is considered Canada's most dangerous road[by whom?] due to frequent accidents, substandard highway construction, avalanche closures and terrible winter driving conditions.
Traffic moving eastbound or westbound between Vancouver Island and the Interior of the province can bypass the Departure Bay–Horseshoe Bay Ferry and the busiest sections of Highway1 in Metro Vancouver using British Columbia Highway 17 (South Fraser Perimeter Road on the Mainland). This route runs from Victoria to Delta and Surrey by way of the Tsawwassen Ferry Terminal, and provides a shortcut that avoids the entire circuitous Vancouver Island route of the Trans-Canada Highway, with its numerous traffic lights and bottlenecks.
Speed limits on the Mainland segment of the Trans-Canada Highway in British Columbia range from 90–100km/h (56–62mph), although in town it can be as low as 50km/h (31mph). A combination of difficult terrain and growing urbanization limits posted speeds on the Vancouver Island section to 50km/h (31mph) in urban areas, 80km/h (50mph) over the Malahat and through suburban areas, and a maximum of 90km/h (56mph) in rural areas.
The Government of British Columbia is attempting to fix the bottleneck at the Ironworkers approach, and widening the highway to six lanes in Abbotsford, to reduce traffic delays. It also is planning on upgrading the entire length of the highway between Kamloops and Alberta to four lanes by 2050 to improve safety and traffic operation. The later plan has several upgrade projects under way, amounting to 20km (12mi) of new four-lane highway under construction. Particularly important is current work to upgrade the remaining 5km (3.1mi) of winding two-lane highway in the Kicking Horse Canyon outside Yoho National Park, which had long been a traffic bottleneck and prone to frequent closure (travel speeds on this section of TCH are often as low as 30km/h). The construction of no fewer than five bridges and extensive blasting is underway to upgrade the Trans-Canada to a 100km/h four-lane highway though the area, with completion scheduled for 2023. To avoid delay to traffic, the construction is largely done at night or during the shoulder season, with a 90-minute-long detour route in effect during those times. A complete closure of the road went into effect from April 19 to May 20, 2022, with additional partial closures from May 24 until fall.[6][7]
The Trans-Canada Highway through the three prairie provinces is 1,667km (1,036mi) long. It starts at the border with British Columbia at Kicking Horse Pass, and runs all the way to the Ontario border at Whiteshell. The highway continues through Alberta, running east for 206km (128mi) as Alberta Highway 1 to Lake Louise, Banff, Canmore and Calgary. This section of the highway passes through Banff National Park, and has significant tourism. The section of Highway1 through Banff National Park was also one of the first highways in North America to have wildlife crossing structures and fencing installed on it. After leaving the mountains it enters Calgary, where it becomes known as 16 Avenue N, a busy six-lane street with many signalized intersections.[8] The northwest and northeast segments of Stoney Trail (Highway201) were completed in 2009, serving as an east–west limited-access highway (freeway) that bypasses the Calgary segment of Highway1 (although Stoney Trail itself is not part of the Trans-Canada Highway network). For the next 293km (182mi) after Calgary, the Trans-Canada Highway continues as a four-lane expressway, with few stops along its route. Medicine Hat is served by a series of six interchanges, after which the Trans-Canada crosses into Saskatchewan on the way to Moose Jaw.[8] The highway mainly travels straight as a four-lane route for most of these sections. The expressway continues 79km (49mi) east to the city of Regina, and skirts around the city on the Regina Bypass, the most expensive infrastructure project in Saskatchewan to date. Beyond Regina, it continues east for 486km (302mi), across the border with Manitoba, to the cities of Brandon and Portage la Prairie, and finally 84km (52mi) east to Winnipeg.[9] The southern portion of Winnipeg's Perimeter Highway (Highway100) is part of the Trans-Canada Highway system, and bypasses the city with a mix of traffic lights and interchanges, while Highway1 continues through central Winnipeg as a signalized arterial road.[9]
With the exception of a 15 km-long stretch of two-lane highway just west of the Ontario border, the entire length of Highway1 through the Prairie Provinces is a four-lane highway. While the only true freeway sections of the route are along the Regina Bypass, in Medicine Hat and between Calgary and Banff, the whole highway is largely stoplight-free, with "split" at-grade intersections forming the vast majority of the junctions. Because the highway has bypasses around all of the major cities traffic congestion is virtually non-existent anywhere on Highway1 through the Prairies. These sections of divided highway are also generally reliable and safe to travel on, unlike sections of Highway1 in British Columbia and Ontario.
The speed limit is restricted to 90km/h (56mph) through national parks in Canada, including Banff National Park. East of Banff, traffic on most of Highway1 through Alberta, Saskatchewan, and Manitoba[10] is limited to 110km/h (68mph), but is 100km/h (62mph) east of Winnipeg.
Alberta Transportation has plans to upgrade its whole length of Highway1 to a four-to-eight-lane freeway by replacing all at-grade intersections with overpasses. However, it has not set a timeline for this project. There has also been talk of re-aligning over 100km (60mi) of Highway1 from its existing route to an upgraded Highway22X when the west sections of Calgary Ring Road are complete, resulting in a designated Trans-Canada Highway bypass route south of the city, but no official announcements have been made.
East of Winnipeg, the highway continues for over 200km (120mi) to Kenora, Ontario. At the provincial border, the expressway downgrades to an arterial highway and the numeric designation of the highway changes from 1 to 17. It is signed with a provincial shield along with a numberless Trans-Canada Highway sign, and continues as an arterial highway along the main route across Northern and Eastern Ontario, until widening out to a freeway at Arnprior, near Ottawa.[11] In Kenora, the Trans-Canada designation includes both the main route through the city's urban core, and the 33.6km (20.9mi)Highway17A bypass route to the north. The existing branch from Kenora continues east for 136km (85mi) to Dryden.[11]This section of highway passes through the Canadian Shield, a rugged forested area with thousands of lakes. There are many cottage communities along this section of the Trans-Canada Highway, some of which have their driveways directly onto the highway.
Highway11/Highway17 proceeds southeast for 65km (40mi) to Thunder Bay, then northeast for 115km (71mi) to Nipigon.[11] An 83-kilometre (52mi) segment of the Trans-Canada Highway between Thunder Bay and Nipigon is commemorated as the Terry Fox Courage Highway.[11] Fox was forced to abandon his cross-country Marathon of Hope run here, and a bronze statue of him was later erected in his honour. The highway is the only road that connects eastern and western Canada. On January 10, 2016, the Nipigon River Bridge suffered a mechanical failure, closing the Trans-Canada Highway for 17 hours; the only alternative was to go through the United States, around the south side of Lake Superior.[12]
Highway17 proceeds east from Nipigon for 581km (361mi) along the northern and eastern coast of Lake Superior. Between Wawa and Sault Ste. Marie, the highway crosses the Montreal River Hill, which sometimes becomes a bottleneck on the system in the winter when inclement weather can make the steep grade virtually impassable.[13] At Sault Ste. Marie, the main route turns eastward for 291km (181mi) to Sudbury.
The mainline route then continues east from Sudbury for 151km (94mi) to North Bay. The northern route rejoins the mainline here, which continues 339km (211mi) to Arnprior where it widens to a freeway and becomes Highway417. The freeway continues to Ottawa passing through the city on Highway417, which is between six and eight lanes wide at this point. In Southern Ontario, the speed limit is generally 80km/h (50mph) on the Trans-Canada, while in Northern Ontario it is 90km/h (56mph). Sections routed along Highway417 outside urban Ottawa feature a higher limit of 110km/h (68mph).[14]
While Highway17 and 417 are largely free from traffic congestion except from minor rush hour delays on Ottawa's stretch of Highway417, the non-freeway sections are subject to frequent closures due to accidents, especially in winter. It is considered a dangerous route due to its extensive outdated sections of winding two-lane highway. Because this section of the highway passes through a largely undeveloped and forested area, collisions with animals are a common cause of accidents.
Ontario plans to eventually extend the 417 freeway to Sudbury, which will upgrade the section of the mainline TCH between Ottawa and Sudbury to four-lane freeway standards. However, there is no funding secured for such a project, as Ontario is currently focusing on extending Highway400 to Sudbury along the Highway69 corridor (which is part of the Georgian Bay TCH route).
It is notable that the Trans-Canada largely bypasses Canada's most heavily populated region, the Golden Horseshoe area of Southern Ontario, which includes Canada's largest city; Toronto. However, a short section of the Central Ontario branch does pass through the rural northeastern edge of Durham Region at both Sunderland and Beaverton, which is officially part of the Greater Toronto Area. Access to Toronto itself from the mainline from Northern Ontario is via the non-TCH southern section of Highway 400, while access from Toronto to Quebec and points east is via Highway 401 (North America's busiest highway and a major national highway in itself),[15] a short non-TCH section of Autoroute 20, and A-30, where the Trans-Canada is joined at A-40 just west of Montreal.
From Ottawa, the Trans-Canada Highway continues as a freeway and proceeds 206km (128mi) east to Montreal, as Highway417 in Ontario (and the Queensway in Ottawa) and Autoroute40 in Quebec.[14] The Trans-Canada assumes the name Autoroute Métropolitaine (also known as "The Met" or "Metropolitan Boulevard") as it traverses Montreal as an elevated freeway. At the Laurentian interchange, in Montreal, the Abitibi route (Highway66, Route117, A-15) rejoins the main TCH line. The TCH then follows Autoroute25 southbound, crossing the St. Lawrence River through the 6-lane Louis-Hippolyte Lafontaine Bridge–Tunnel, and proceeds northeast on Autoroute20 for 257km (160mi) to Lévis (across from Quebec City).
East of Lévis, the Trans-Canada Highway continues on Autoroute20 following the south bank of the St. Lawrence River to a junction just south of Rivière-du-Loup, 173km (107mi) northeast of Lévis. At that junction, the highway turns southeast and changes designation to Autoroute85 for 13km (8mi), and then downgrades from a freeway to Route185, a non-Autoroute (not limited-access) standard highway until Saint-Louis-du-Ha! Ha! where Autoroute 85 resumes once again. The portion from Autoroute20 to Edmundston, New Brunswick is approximately 120km (75mi) long.[14]
Since the Trans-Canada Highway for the most part follows Quebec's Autoroute System, which is always composed of a minimum four-lane freeway, travel through Quebec is generally, safe, fast and congestion free. The exception is the route through Montreal, which can be prone to traffic congestion. However, drivers can bypass the city on the tolled Autoroute 30, which is not part of the Trans-Canada.
The maximum speed limit on the Quebec Autoroute System (including the TCH) is a strictly enforced 100km/h (62mph). However, the speed limit may be lower in select spots, such as through tunnels or major interchanges.
Quebec is currently working on upgrading the last remaining 36 km-long two-lane section of Trans-Canada Highway along 185 to an Autoroute, with 9km (5.6mi) of new freeway opened in 2021, and another 20km (12.4mi) of freeway currently under construction. Once this project is complete, the two sections of Autoroute 85 will be joined, and all of Quebec's Mainline Trans-Canada Highway route will be minimum four-lane freeway standards. This will also result in the TCH becoming a continuous freeway from Arnprior, Ontario, to Lower South River, Nova Scotia.
The Trans-Canada Highway crosses into New Brunswick and becomes Route2 just northwest of Edmundston. From Edmundston, the highway (again signed exclusively with the TCH shield) follows the Saint John River Valley, running south for 170km (110mi) to Woodstock (parallelling the Canada–US border) and then east for another 102km (63mi) to pass through Fredericton. 40km (25mi) east of Fredericton, the Saint John River turns south, whereby the highway crosses the river at Jemseg and continues heading east to Moncton another 135km (84mi) later. On November 1, 2007, New Brunswick completed a 20-year effort to convert its entire 516km (321mi) section of the Trans-Canada Highway into a four-lane limited-access divided highway. The highway has a speed limit of 110km/h (68mph)[14] on most of its sections in New Brunswick.
New Brunswick was the first province where the main route of the Trans-Canada Highway was made entirely into a four-lane limited-access divided highway.
From Moncton, the highway continues southeast for 54km (34mi) to a junction at Aulac close to the New Brunswick–Nova Scotia border (near Sackville). Here, Trans-Canada Highway again splits into two routes, with the main route continuing to the nearby border with Nova Scotia as Route2, and a 70km (43mi) route designated as Route16 which runs east to the Confederation Bridge at Cape Jourimain.[14]
From the New Brunswick border, the main Trans-Canada Highway route continues east into Nova Scotia at Amherst, where it settles onto Nova Scotia Highway 104. Southeast of Amherst, near Thomson Station, the highway traverses the Cobequid Pass, a 45km (28mi)tolled section ending at Masstown, before passing by Truro, where it links with Highway102 to Halifax, 117km (73mi) east of the New Brunswick border. Halifax, like Toronto, is a provincial capital that the Trans-Canada Highway does not pass through. Beyond Truro, the highway continues east for 57km (35mi) to New Glasgow where it meets Highway106, before continuing to the Canso Causeway which crosses the Strait of Canso onto Cape Breton Island near Port Hawkesbury. From the Canso Causeway, the highway continues east, now designated as Highway105 on Cape Breton Island, until reaching the Marine Atlantic ferry terminal at North Sydney.[14]
From North Sydney, a 177km (110mi) ferry route, operated by the Crown corporation Marine Atlantic, continues the highway to Newfoundland, arriving at Channel-Port aux Basques, whereby the Trans-Canada Highway assumes the designation of Highway1 and runs northeast for 219km (136mi) through Corner Brook, east for another 352km (219mi) through Gander and finally ends at St. John's, another 334km (208mi) southeast, for a total of 905km (562mi) crossing the island.[14] The majority of the Trans-Canada Highway in Newfoundland is undivided, though sections in Corner Brook, Grand Falls-Windsor, Glovertown and a 75km (47mi) section from Whitbourne to St. John's are divided.[14]
Although there does not appear to be any nationally sanctioned "starting point" for the entire Trans-Canada Highway system, St. John's has adopted this designation for the section of highway running in the city. The foot of East White Hills Road in St. John's, near Logy Bay Road, would be a more precise starting point of the highway, where the road meets and transfers into the start of the Trans-Canada Highway. The terminus of the Trans-Canada Highway in Victoria, located at the foot of Douglas Street and Dallas Road at Beacon Hill Park, is also marked by a "mile zero" monument. St. John's downtown arena, Mary Brown's Centre, was originally branded under naming rights as "Mile One Centre" in reference to the geography of the region.[16][17]
The usage of miles instead of kilometres at both designations dates back to when the Trans-Canada Highway was completed in 1962, prior to metrication in Canada.
The Yellowhead Highway is a 2,859km (1,777mi) highway in Western Canada, running from Masset, British Columbia, to where it intersects Highway1 (Trans-Canada Highway) just west of Portage la Prairie, Manitoba. It is designated as Highway16 in all four provinces that it passes through (British Columbia, Alberta, Saskatchewan and Manitoba). It follows a more northerly east–west route across Western Canada than the main TCH and passes through fewer cities, with Edmonton being the largest on the route. Other major municipalities on the route include Prince Rupert, Prince George, Lloydminster and Saskatoon. The Yellowhead Highway is most well known for passing through Jasper National Park in Alberta, where it crosses the Continental Divide through its namesake Yellowhead Pass. Since it carries significantly less traffic than its more southerly counterpart, the Yellowhead is almost exclusively a two-lane highway in British Columbia and Manitoba, and is only partially upgraded to four-lane expressway standards in Alberta and Saskatchewan. Until recently,[when?] the Yellowhead Highway had its own unique highway number signs, but they have now mostly been replaced with standard maple-leaf Trans-Canada Highway signs, with numberless Yellowhead shields posted adjacent to them.
The 1,547km (961mi) section of Highway 71 and Highway 11 between Kenora, Ontario and North Bay, Ontario is considered part of the Trans-Canada Highway. This highway first runs south of the Main TCH route between Kenora and Thunder Bay, passing through the town of Fort Frances on the U.S. border. Then, after running concurrently with the main Trans-Canada Highway route (Highway17) it splits off to the north, running through a vast and sparsely-populated area of northern Ontario. This highway sees little long-distance traffic compared to the main route, beside heavy transport trucks looking to avoid the significant elevation changes along the Lake Superior route. Despite being over 100 km longer, it is much flatter and the transit time for heavy hauling is usually the same. The area is also not well known as a tourist destination outside of fishing tours, which are often fly-in. A much shorter 60km (37mi) section of Highway66 connects another northern Trans-Canada Highway route to Quebec's Highway 117, which itself continues the TCH route to Montreal after connecting with Autoroute 15. The main Highway11 continues south until it intersects the main Trans-Canada Highway route (Highway17) in North Bay. Except for the southernmost stretches south of Labelle these highways are two-lane undivided routes.
The southern Ontario Trans-Canada Highway route is even more abstract than the northern ones, as it uses four different provincial highways, and is largely non-functional as a major long distance corridor due to its roundabout route and the complete avoidance of the Toronto area. It is a 671km-long alternate route to Highway17 (the mainline TCH) between Sudbury and Ottawa. It passes through several major communities, including Orillia and Peterborough. Because it passes closer to major population centres, this section of the TCH sees higher traffic volumes. It is made up of various sections of freeways, expressways and two-lane routes.
Another spur route of the Trans-Canada Highway splits off the mainline in eastern New Brunswick. This route connects to Prince Edward Island across the 13 km-long Confederation Bridge, crosses the central part of Prince Edward Island, including through the provincial capital of Charlottetown, before crossing back to the mainland on a ferry. This length of the route is 234 km, and consists of New Brunswick Highway16, Prince Edward Island Highway1 and Nova Scotia Highway106. This leg of the Trans-Canada Highway sees moderately high traffic volumes and is an important tourist route. The Confederation Bridge is often viewed as an attraction in itself. Although the highway is mostly a two-lane route, portions of the route are built as two-lane expressways.
Two short bypasses are also considered part of the Trans-Canada Highway system. These include the 42-kilometre-long (26mi)Perimeter Highway100 bypass around Winnipeg, which provides an expressway standard alternative to the crowded Highway1 in the city centre; and the 34-kilometre-long (21mi) two-lane Kenora Bypass (Highway17A) which is a two-lane route that bypasses the entire town to the north.
Early on, much of the route of the Trans-Canada Highway was first explored in order to construct the Canadian Pacific Railway in the late 19th century, a route which much of the mainline TCH route later ended up following.
The Trans-Canada Highway was not the first road across Canada. In British Columbia, the highway was predated by the Crowsnest Highway, the Big Bend Highway and the Cariboo Highway, all of which were constructed during the Great Depression era. Many of the earlier highways in British Columbia were largely gravel, and had many frequent inland ferry crossings at wide rivers and lakes. In Alberta. the section between Calgary and Banff was predated by the Morley Trail (now Highway1A). which was drivable starting in the 1910s and paved in the 1930s. The first route over the Central Canadian Rockies to connect Calgary to British Columbia was the Banff–Windermere Parkway, which was opened in 1922 and is now numbered as Highway93. Sections of road across the Prairies have also existed since the 1920s. A gravel road connection across northern Ontario (Highway17) was constructed starting in 1931. While this section was largely open by the late 1930s, it was not fully completed until 1951 (in large part due to World War II interrupting construction). However, despite the gap, vehicles could still cross the county by getting ferried around the relatively short section of incomplete highway by either rail or water.
Opening
The system was approved by the Trans-Canada Highway Act of 1949,[18] with construction commencing in 1950.[19] The highway officially opened in 1962, with the completion of the Rogers Pass section of highway between Golden and Revelstoke. This section of highway bypassed the original Big Bend Highway, the last remaining section of gravel highway on the route. Upon its original completion, the Trans-Canada Highway was the longest uninterrupted highway in the world.[20] Construction on other legs continued until 1971 when the last gap on Highway16 was completed in the Upper Fraser Valley east of Prince George, at which point the highway network was considered complete.
Since completion (1960–2000)
When the Trans-Canada Highway first opened, it was almost exclusively a two-lane route for its whole length across the country. While at the time it was considered a major improvement to the gravel roads and ferries it replaced, it was soon found insufficient to handle the growing traffic volumes. In response, several provinces began to construct realignments, freeway upgrades and twin sections of highway in order to improve traffic flow and safety.
In British Columbia's Lower Mainland, the Upper Levels Freeway alignment was opened in 1960 with the completion of the Second Narrows Crossing, which allowed the Trans-Canada Highway to bypass downtown Vancouver's streets and the narrow Lions Gate Bridge. The four-lane Upper Levels Freeway was relatively-crudely constructed, with narrow lanes, low overpasses and no proper merge ramps. It remains in this state in the present day. Between 1962 and 1964, Highway1 was rerouted onto a new four-lane freeway bypass between Vancouver and Chilliwack. This section of highway was originally part of British Columbia's own "400" series of highways, until the designation was replaced by Highway1. A freeway alignment on the Trans-Canada Highway between Chilliwack and Hope opened in 1986. The opening of the Cassiar Tunnel in 1990 bypassed the last sets of signal lights in Vancouver rendering the whole alignment of the Trans-Canada Highway through the Lower Mainland a freeway. All bypassed sections of the highway were absorbed into various urban and rural road networks. The older freeways in the Lower Mainland were largely built as a parkway design, with wide forested medians and low overpasses (a road configuration that was common across North America at the time). The opening of the Coquihalla Highway in 1986 left much of the Trans-Canada Highway through the Fraser Canyon functionally obsolete, with the freeway bypass shortening the drive between Hope and Kamloops by 90 minutes. However, the route was retained as part of the Trans-Canada Highway system, despite being considered nothing more than a scenic route in the present. The opening of the Coquihalla was also an economic disaster for many of the towns along the Fraser Canyon section of the Trans-Canada Highway, since most of the travel and tourism business along the route quickly dried up when most of the traffic took the new highway. The towns continue to be largely deprived of wealth, and some are close to being abandoned. On the other hand. Merritt, located midway up the new Coquihalla highway, ended up booming, and continues to grow as a tourism and travel centre into the present. The Coquihalla project also realigned Highway1 (TCH) to a new freeway bypass around Kamloops. Plans for a freeway to bypass or eliminate traffic congestion and road hazards along the heavily travelled route from Victoria to Nanaimo on Vancouver Island were cancelled during the recession that followed the 1987 stock market crash.
In Alberta, between 1964 and 1972, the Trans-Canada Highway was completely rerouted from its former two-lane alignment along the Bow River to a new, more direct, four-lane freeway between Banff and Calgary, resulting in the bypassing of several towns, such as Canmore. Prior to this upgrade, one of the first traffic circles in Canada existed on Highway1 at the "gateway" junction for Banff from at least as early as the 1950s. the current interchange on Highway1 for Banff Avenue now occupies the site. In the rest of Banff National Park, much of the predecessor Highway1 parkway was bypassed by a new two-lane route in the 1960s. The original route between Banff and Lake Louise remains as the Bow Valley Parkway and Lake Louise Drive, while a section over Kicking Horse Pass was abandoned and is now part of the Great Divide Trail. Between 1973 and 1990 the highway was twinned from Calgary to the Saskatchewan Border. In 1970 plans were made for a six-to-eight-lane freeway to carry the Trans-Canada Highway though the heart of North Calgary, but the plan was soon dropped due to citizen outcry.
Between Ottawa and the Ontario–Quebec border, the Trans-Canada Highway designation was taken from the two-lane Highway17 and applied to the existing Highway417 freeway in 1997–98. On April 1, 1997, the Ministry of Transportation of Ontario (MTO) transferred the responsibility of maintenance and upkeep along 14.2km (8.8mi) of Highway17 east of "the split" with Highway417 to Trim Road (Regional Road57) to the Regional Municipality of Ottawa-Carleton, a process commonly referred to as downloading. The Regional Municipality then designated the road as Regional Road 174. Despite the protests of the region that the route served a provincial purpose, a second round of transfers saw Highway17 within Ottawa downloaded entirely on January 1, 1998, adding an additional 12.8km (8.0mi) to the length of Regional Road174.[21] The highway was also downloaded within the United Counties of Prescott and Russell, where it was redesignated as County Road17.[22] The result of these transfers was the truncation of Highway17 at the western end of Highway417.[23] 1990 saw the opening of the two-lane Kenora Bypass, providing through traffic with a way to avoid the congested town.
Starting in the 1960s, Quebec began to build its Autoroute network. Many sections of Trans-Canada Highway were upgraded to freeway standards during that era of highway construction.
Starting in 1987, New Brunswick began to upgrade its section of TCH to 4 lanes. Work to make the route a full freeway began in the late 1990s and was completed in 2007.
The 13 km-long Confederation Bridge connecting PEI to New Brunswick opened in 1997. Replacing the ferry that previously serviced that route, it was hailed as a major accomplishment.
Recent improvements (2000–present)
In 2000 and 2001, Transport Canada considered funding an infrastructure project to have the full Trans-Canada system converted to limited-access divided highways. Although construction funding was made available to some provinces for portions of the system, the federal government ultimately decided not to pursue a comprehensive limited-access highway conversion. Opposition to funding the limited-access upgrade was due to low traffic levels on parts of the Trans-Canada Highway.
Prior to the start of the Great Recession in 2008, the highway underwent some upgrades through the Rocky Mountains from Banff National Park to Golden, British Columbia. A major piece of this project was completed on August 30, 2007, with the new Park Bridge and Ten Mile Hill sections opening up 16km (9.9mi) of new four-lane highway. Other smaller four-lane upgrade projects on the Trans-Canada Highway in the interior of British Columbia were also built around the same time. As part of the Gateway Program, 37km (23mi) of congested four-lane Highway1 freeway in Metro Vancouver were upgraded to a more modern eight-lane build out starting in 2012. This project continues into the present, with the current goal of rebuilding the freeway to a modern, minimum six-lane layout from Langley to Abbotsford by 2025.
The twinning of the highway in Alberta's Banff National Park continued with four-lane highway opening as far as the Highway93 junction north of Lake Louise by the winter of 2010. Parks Canada completed twinning the final 8.5km (5.3mi) of Highway1 between Lake Louise and the British Columbia border, with the new alignment opened to traffic on June 12, 2014[24] making the whole length of Alberta's main Trans-Canada Highway route a minimum four lanes. Stoney Trail began construction in 2005, and was usable as a bypass around Calgary when its northeastern section opened in 2010. Although not officially part of the Trans-Canada Highway system, Stoney Trail plays a critical role in providing through traffic on the Trans-Canada Highway with a way around the city.
During the 2000s much of the Trans-Canada Highway through Saskatchewan and Manitoba was twinned. In 2019 the Regina Bypass opened, resulting in the Trans-Canada Highway being realigned around the city, and bypassing a section of heavily-signalized arterial road on Victoria Avenue.
The 2010s saw the improvement of other routes in the Trans-Canada Highway system as well. Ontario Highway400 began to be extended towards Sudbury, replacing Highway69 and resulting in a freeway alignment for part of the Southern Ontario Trans-Canada Highway Route. Work on this project is continuing, with almost 25km (16mi) of freeway currently under construction.
Edmonton is currently attempting to upgrade its urban section of Highway16 to a six-lane freeway. Large amounts of Highway16 in Alberta were twinned during the 2000s.
Despite these many upgrades, over half of the mainline Trans-Canada highway still remains in its original two-lane state, and only about 15 per cent of the mainline's length is composed of freeway comparable to that of the Interstate Highway System.
In 2012, a series of free public electric vehicle charging stations were installed along the main route of the highway by a private company, Sun Country Highway, permitting electric vehicle travel across the entire length, as demonstrated by the company's president, Kent Rathwell, in a publicity trip from St John's, NL to Victoria, BC in a Tesla Roadster. As of 2012[update], this made the TCH the longest electric-vehicle-ready highway in the world.[25][26]
Future
No national plan for upgrading the Trans-Canada Highway exists, and all planning is currently done by the individual provinces. However, as with other routes in Canada's National Highway System, the federal government is required to cost-share for upgrades funded by the provinces. Currently, there are five large-scale highway improvement projects on the Trans-Canada Highway Network.
Quebec is working on completing Autoroute 85, bringing the last two-lane section of the mainline highway in Quebec up to four-lane freeway standards. As of September2021[update], only 7km (4.3mi) of two-lane highway had not yet been addressed. The rest either had been completed or was currently under construction.
As of September2021[update], Ontario was attempting to extend Highway400 to Sudbury, which will carry the Southern Ontario TCH designation once complete. Around 80km (50mi) of highway remained to be upgraded to freeway standard, with approximately 25km (16mi) of new freeway under construction. The project was originally expected to be complete in 2021 but had its date pushed back.
As of September2021[update], British Columbia was planning on upgrading the 420km (260mi) long section of TCH between Kamloops and Alberta to four lanes by 2050. The project goals do not include an eventual freeway upgrade, and it is likely that the signalized sections of highway in Kamloops, Salmon Arm, Revelstoke and Golden will remain. Around 16km (9.9mi) of four-lane highway were under construction, with 6km (3.7mi) more planned to start in 2022. Around a quarter of the length of highway between Kamloops and Alberta is now four lanes wide. At the current rate of construction, the project will likely not be completed until the 2070s. However, some of the most difficult sections have been completed, meaning that it may be easier to upgrade the remaining sections of highway to four lanes. Some of the highway in this section is under the jurisdiction of Parks Canada, specifically the sections through Mount Revelstoke, Glacier and Yoho National Parks, which means that Parks Canada will have to implement its own four-lane upgrade program in order for the provincial government to accomplish its goal.
The City of Edmonton is upgrading its urban section of Highway 16 (TCH) to a six-lane freeway by replacing all signal lights with overpasses. The route is already largely a freeway, but seven signalized intersections remain. The project is expected to be finished by 2026.[27]
As of September2021[update], British Columbia was planning on upgrading 36km (22mi) of Highway 1 in the Lower Mainland as part of its Fraser Valley Highway improvement program. The four-lane freeway is over-congested, and many of the overpasses are in poor shape. The project intends to rebuild most of the interchanges and overpasses and widen the highway to six lanes. The first 4km (2.5mi) of this project opened in 2020, with 10km (6.2mi) more expected to be complete in 2025.
Apart from the major programs, many smaller scale projects exist on the highway in order to either rehabilitate the aging infrastructure or make minor traffic improvements.
Alberta had long term plans to upgrade both of its Trans-Canada Highway routes to a minimum four-lane freeway standard, but has not set a timeline for doing so.
Ontario hopes to eventually extend the 417 freeway to Sudbury, which will carry the mainline TCH route, but it has not set a timeline for doing so.
The Crowsnest Highway is an east-west highway in British Columbia and Alberta, Canada. It stretches 1,161 km (721 mi) across the southern portions of both provinces, from Hope, British Columbia to Medicine Hat, Alberta, providing the shortest highway connection between the Lower Mainland and southeast Alberta through the Canadian Rockies. Mostly two-lane, the highway was officially designated in 1932, mainly following a mid-19th-century gold rush trail originally traced out by an engineer named Edgar Dewdney. It takes its name from the Crowsnest Pass, the location at which the highway crosses the Continental Divide between British Columbia and Alberta.
Route 1 is a highway in the southern part of the Canadian province of New Brunswick. It begins in the west from the Canada–United States border at St. Stephen, and runs east for 239.11 kilometres (148.58 mi) to Route 2 at River Glade.
Highway 1 is a provincial highway in British Columbia, Canada, that carries the main route of the Trans-Canada Highway (TCH). The highway is 1,047 kilometres (651 mi) long and connects Vancouver Island, the Greater Vancouver region in the Lower Mainland, and the Interior. It is the westernmost portion of the main TCH to be numbered "Highway 1", which continues through Western Canada and extends to the Manitoba–Ontario boundary. The section of Highway 1 in the Lower Mainland is the second-busiest freeway in Canada, after Ontario Highway 401 in Toronto.
King's Highway 17, more commonly known as Highway 17, is a provincially maintained highway and the primary route of the Trans-Canada Highway through the Canadian province of Ontario. It begins at the Manitoba boundary, 50 km (31 mi) west of Kenora, and the main section ends where Highway 417 begins just west of Arnprior. A small disconnected signed section of the highway still remains within the Ottawa Region between County Road 29 and Grants Side Road. This makes it Ontario's longest highway.
Route 2 is a major provincial highway in the Canadian province of New Brunswick, carrying the main route of the Trans-Canada Highway in the province. The highway connects with Autoroute 85 at the border with Quebec and Highway 104 at the border with Nova Scotia, as well as with traffic from Interstate 95 in the U.S. state of Maine via the short Route 95 connector. A core route in the National Highway System, Route 2 is a four-lane freeway in its entirety, and directly serves the cities of Edmundston, Fredericton, and Moncton.
King's Highway 417, commonly referred to as Highway 417 and as the Queensway through Ottawa, is a 400-series highway in the Canadian province of Ontario. It connects Ottawa with Montreal via A-40, and is the backbone of the highway system in the National Capital Region. Within Ottawa, it forms part of the Queensway west from Highway 7 to Ottawa Road 174. Highway 417 extends from the Quebec border, near Hawkesbury, to Arnprior, where it continues westward as Highway 17. Aside from the urban section through Ottawa, Highway 417 passes through farmland that dominates much of the fertile Ottawa Valley.
Autoroute 20 is a Quebec Autoroute, following the Saint Lawrence River through one of the more densely populated parts of Canada, with its central section forming the main route of the Trans-Canada Highway from the A-25 interchange to the A-85 interchange. At 585 km (363.5 mi), it is the longest Autoroute in Quebec. It is one of two main links between Montreal and Quebec City; the other is the A-40.
Autoroute 40, officially known as Autoroute Félix-Leclerc outside Montreal and Metropolitan Autoroute/Autoroute Métropolitaine within Montreal, is an Autoroute on the north shore of the St. Lawrence River in the Canadian province of Quebec. It is one of the two major connections between Montreal and Quebec City, the other being Autoroute 20 on the south shore of the St. Lawrence. Autoroute 40 is currently 347 km (215.6 mi) long. Between the Ontario–Quebec boundary and the interchange with Autoroute 25, the route is signed as part of the Trans-Canada Highway.
Autoroute 50 is an Autoroute in western Quebec, Canada. It links Canada's National Capital Region (Gatineau) and the Greater Montreal area (Mirabel).
Route 185 is part of the Trans-Canada Highway. It travels from Saint-Antonin to Saint-Louis-du-Ha! Ha!, a distance of about 41 km (25.5 mi). It connects the 2 sections of Autoroute 85 and is the former designation for all of A-85.
Autoroute 73 is an autoroute in Quebec, Canada. Following a northwest-southeast axis perpendicular to the Saint Lawrence River, the A-73 provides an important freeway link with regions north and south of Quebec City, the capital of the province. It also intersects with Autoroute 20 and Autoroute 40 - one of only three Quebec autoroutes to do so. The A-73 begins less than 40 kilometres from the U.S. border in Quebec's Beauce region, traverses metropolitan Quebec City, and ends in the Laurentian Mountains. Civic, political, and business leaders in regions north and south of the A-73's termini have lobbied the Quebec government to extend the autoroute. While the four-laning of Route 175 to Saguenay has alleviated concerns in the north about safety and connectivity, Quebecers in the Beauce continue to advocate for extending the A-73 to the U.S. border, towards the Armstrong–Jackman Border Crossing and U.S. Route 201 within Maine.
Alberta Provincial Highway No. 3, commonly referred to as Highway 3 and officially named the Crowsnest Highway, is a 324-kilometre (201 mi) highway that traverses southern Alberta, Canada, running from the Crowsnest Pass through Lethbridge to the Trans-Canada Highway in Medicine Hat. Together with British Columbia Highway 3 which begins in Hope, it forms an interprovincial route that serves as an alternate to the Trans-Canada from the Lower Mainland to the Canadian Prairies.
Alberta Provincial Highway No. 1, commonly referred to as Highway 1, is a major east–west highway in Southern Alberta that forms the southern mainline of the Trans-Canada Highway. It runs from the British Columbia border near Lake Louise through Calgary to the Saskatchewan border east of Medicine Hat. It continues as Highway 1 into both provinces. It spans approximately 534 km (332 mi) from Alberta's border with British Columbia in the west to its border with Saskatchewan in the east. The route is a divided 4-lane expressway throughout the province with the exception of a section in central Calgary where it is an arterial thoroughfare and Urban Boulevard carrying 4 to 6 lanes. The highway is a freeway between the Sunshine exit near the town of Banff and Home Road in Calgary. Other rural sections have at grade intersections with Interchanges only at busier junctions. Twinning of the final 8.5 km (5.3 mi) of Highway 1 between Lake Louise and the British Columbia border was completed by Parks Canada and opened to traffic on June 12, 2014 making the whole length of Alberta Highway 1 a divided minimum 4-lane route.
Alberta Provincial Highway No. 1A is the designation of two alternate routes off the Alberta portion of Trans-Canada Highway 1. However, it is not the only name used for spurs off Highway 1 - Highway 1X is another such designation. Despite these highways being suffixed routes of Highway 1, they are not part of the Trans-Canada Highway network, and are signed with Alberta's provincial primary highway shields instead of the Trans-Canada shields used for Highway 1.
Autoroute 30 (A-30), or the Autoroute de l'Acier is an Autoroute in Quebec, Canada. Construction of the A-30 dates back to the early days of autoroute construction in the 1960s. Originally called Highway 3, the A-30 was designed to replace Route 132 as the main artery linking the communities along the South Shore of the St. Lawrence River. The A-30 was originally intended to begin at the U.S. border near Dundee and end at Saint-Pierre-les-Becquets. In the late 1970s an eight-year moratorium on new autoroute construction in favour of public transport by the Parti Québécois prevented implementation of that plan.
Alberta Provincial Highway No. 11, commonly referred to as Highway 11 and officially named the David Thompson Highway, is a provincial highway in central Alberta, Canada. It runs for 318 km (198 mi) from Highway 93 at Saskatchewan River Crossing near Mount Sarbach in Banff National Park east to Highway 12 near Nevis. It passes by Nordegg and through Rocky Mountain House, Sylvan Lake and Red Deer along its course. The highway is named after David Thompson, a British-Canadian fur trader, surveyor, and map-maker who explored the area between Rocky Mountain House and Kootenae House through Howse Pass.
Autoroute 85 is a Quebec Autoroute and the route of the Trans-Canada Highway in the province's Bas-Saint-Laurent region, also known as Autoroute Claude-Béchard. It is currently under construction with committed Federal and Provincial funding for its completion, with an estimated completion date of 2026. Once this upgrade is completed, it will close the last gap in the nearly continuous freeway section of the Trans-Canada between Arnprior, Ontario, and Antigonish, Nova Scotia, and for an even longer interprovincial freeway route between Windsor, Ontario and Halifax, Nova Scotia. Running between Rivière-du-Loup and a junction with New Brunswick Route 2 at the Quebec-New Brunswick border, A-85 when complete will be the only controlled access highway link between the Maritime Provinces and the rest of the country. A-85 is projected to be approximately 100 km (60 mi) long when construction is complete and is intended to replace Route 185, which has been called one of the deadliest highways in Canada.
Transportation in North America is performed through a varied transportation system, whose quality ranges from being on par with a high-quality European motorway to an unpaved gravelled back road that can extend hundreds of miles. There is also an extensive transcontinental freight rail network, but passenger railway ridership is lower than in Europe and Asia.
British Columbia Highway 3, officially named the Crowsnest Highway, is an 841-kilometre (523 mi) highway that traverses southern British Columbia, Canada. It runs from the Trans-Canada Highway (Highway 1) at Hope to Crowsnest Pass at the Alberta border and forms the western portion of the interprovincial Crowsnest Highway that runs from Hope to Medicine Hat, Alberta. The highway is considered a Core Route of the National Highway System.
16 Avenue N is a major road in Calgary, Alberta, that forms a 26.5-kilometre (16.5 mi) segment of Highway 1 and connects Calgary to Banff and Medicine Hat. It is a four to six-lane principal arterial expressway at its extremities, but is an urban arterial road between the Bow River and Bowness Road, and also between Crowchild Trail and Deerfoot Trail. Due to Calgary's quadrant system, it is known as 16 Avenue NW west of Centre Street and 16 Avenue NE to the east.
