King's Highway 401, commonly referred to as Highway 401 and also known by its official name as the Macdonald–Cartier Freeway or colloquially referred to as the four-oh-one, is a controlled-access 400-series highway in the Canadian province of Ontario. It stretches 828 kilometres (514 mi) from Windsor in the west to the Ontario–Quebec border in the east. The part of Highway 401 that passes through Toronto is North America's busiest highway, and one of the widest. Together with Quebec Autoroute 20, it forms the road transportation backbone of the Quebec City–Windsor Corridor, along which over half of Canada's population resides. It is also a Core Route in the National Highway System of Canada. The route is maintained by the Ministry of Transportation of Ontario (MTO) and patrolled by the Ontario Provincial Police. The speed limit is 100 km/h (62 mph) throughout the majority of its length, with the remaining exceptions being the posted 80 km/h (50 mph) limit westbound in Windsor, in most construction zones, and the 110 km/h (68 mph) speed limit on the 40 km (25 mi) stretch between Windsor and Tilbury that was raised on April 22, 2022, the 7 km (4.3 mi) extension east of the aforementioned, the 35 km (22 mi) stretch between Highway 35 / 115 and Cobourg, the 44 km (27 mi) stretch between Colborne and Belleville, the 66 km (41 mi) stretch between Belleville and Kingston, and the 107 km (66 mi) stretch between Highway 16 and the east end of the highway that were raised on July 12, 2024.
The Queen Elizabeth Way (QEW) is a 400-series highway in the Canadian province of Ontario linking Toronto with the Niagara Peninsula and Buffalo, New York. The highway begins at the Canada–United States border on the Peace Bridge in Fort Erie and travels 139.1 kilometres (86.4 mi) around the western end of Lake Ontario, ending at Highway 427 as the physical highway continues as the Gardiner Expressway into downtown Toronto. The QEW is one of Ontario's busiest highways, with an average of close to 250,000 vehicles per day on some sections.
The 400-series highways are a network of controlled-access highways in the Canadian province of Ontario, forming a special subset of the provincial highway system. They are analogous to the Interstate Highway System in the United States or the Autoroute system of neighbouring Quebec, and are regulated by the Ministry of Transportation of Ontario (MTO). The 400-series designations were introduced in 1952, although Ontario had been constructing divided highways for two decades prior. Initially, only Highways 400, 401 and 402 were numbered; other designations followed in the subsequent decades. To this day, not all controlled-access highways in Ontario are a part of the 400-series highway network. The network is situated almost entirely in Southern Ontario, although Highway 400 extends into the more remote northern portion of the province.
The Conestoga Parkway, officially the Kitchener–Waterloo Expressway, is a controlled-access highway in the Canadian province of Ontario, located entirely within the Regional Municipality of Waterloo. The 20.7-kilometre (12.9 mi) route travels east and then north through the cities of Kitchener and Waterloo, and is connected to Highway 401 via Highway 8 and King Street East. The name Conestoga Parkway is not a formal designation, but rather a local name applied to the divided expressway portions of Highway 7, Highway 8 and Highway 85 through Kitchener and Waterloo. The Ministry of Transportation of Ontario (MTO), which built and maintains the route, refers to it as the Kitchener–Waterloo Expressway.
The Ontario Provincial Highway Network consists of all the roads in Ontario maintained by the Ministry of Transportation of Ontario (MTO), including those designated as part of the King's Highway, secondary highways, and tertiary roads. Components of the system—comprising 16,900 kilometres (10,500 mi) of roads and 2,880 bridges —range in scale from Highway 401, the busiest highway in North America, to unpaved forestry and mining access roads. The longest highway is nearly 2,000 kilometres (1,200 mi) long, while the shortest is less than a kilometre. Some roads are unsigned highways, lacking signage to indicate their maintenance by the MTO; these may be remnants of highways that are still under provincial control whose designations were decommissioned, roadway segments left over from realignment projects, or proposed highway corridors.
King's Highway 3, commonly referred to as Highway 3, is a provincially maintained highway in the Canadian province of Ontario which travels parallel to the northern shoreline of Lake Erie. It has three segments, the first of which travels from the Ambassador Bridge in Windsor to Highway 77 in Leamington. The second portion begins at Talbotville Royal outside of St. Thomas at Highway 4, and travels to the western city limits of Port Colborne. The road is regionally maintained within Port Colborne as Niagara Regional Road 3, but regains its provincial designation at Highway 140. Its third and final terminus is at Edgewood Park, within the Fort Erie town limits. From there, the road continues as Niagara Regional Road 3 to the Peace Bridge, where drivers can cross to the United States. The total length of Highway 3 is 248.9 or 258.2 km, consisting of 49.2 km (30.6 mi) from Windsor to Leamington, 187.9 km (116.8 mi) from Talbotville Royal to Port Colborne and 21.1 km (13.1 mi) from Port Colborne to Edgewood Park.
King's Highway 427, also known as Highway 427 and colloquially as the 427, is a 400-series highway in the Canadian province of Ontario that runs from the Queen Elizabeth Way (QEW) and Gardiner Expressway in Toronto to Major Mackenzie Drive in Vaughan. It is Ontario's second busiest freeway by volume and the third busiest in North America, behind Highway 401 and Interstate 405 in California. Like Highway 401, a portion of the route is divided into a collector-express system with twelve to fourteen continuous lanes. Notable about Highway 427 are its several multi-level interchanges; the junctions with the QEW/Gardiner Expressway and Highway 401 are two of the largest interchanges in Ontario and were constructed between 1967 and 1971, while the interchanges with Highway 409 and Highway 407 were completed in 1992 and 1995, respectively.
King's Highway 7, commonly referred to as Highway 7 and historically as the Northern Highway, is a provincially maintained highway in the Canadian province of Ontario. At its peak, Highway 7 measured 716 km (445 mi) in length, stretching from Highway 40 east of Sarnia in Southwestern Ontario to Highway 17 west of Ottawa in Eastern Ontario. However, due in part to the construction of Highways 402 and 407, the province transferred the sections of Highway 7 west of London and through the Greater Toronto Area to county and regional jurisdiction. The highway is now 535.7 km (332.9 mi) long; the western segment begins at Highway 4 north of London and extends 154.1 km (95.8 mi) to Georgetown, while the eastern segment begins at Donald Cousens Parkway in Markham and extends 381.6 km (237.1 mi) to Highway 417 in Ottawa.
The E. C. Row Expressway is a municipal expressway in the city of Windsor, Ontario, Canada. It divides the city in half as it crosses it between the Ojibway Parkway in the west and Banwell Road in the east, a distance of 15.4 kilometres (9.6 mi). It was built between 1971 and 1983, reaching completion across the city on June 9, 1983. It was part of Highway 2 and Highway 18 until the province transferred ownership and responsibility for the route to the City of Windsor on April 1, 1997. In 2015, the westernmost 3 kilometres (1.9 mi) was significantly upgraded as part of the Highway 401 extension project. The freeway is named after Edgar Charles Row, the president of Chrysler Canada between 1951 and 1956.
King's Highway 404, also known as Highway 404 and colloquially as the 404, is a 400-series highway in the Canadian province of Ontario. A continuation of the municipal Don Valley Parkway (DVP) north of Highway 401, it connects Toronto with East Gwillimbury. The 50.1-kilometre (31.1 mi) controlled-access freeway also connects with Highway 407 in Markham, which formed the northeastern ring road of the Greater Toronto Area until the opening of Highway 412 in 2016. Highway 404 provides access to the eastern edge of Richmond Hill, Aurora and Newmarket and the western edge of Whitchurch-Stouffville, in addition to the southern edge of Keswick.
King's Highway 400, commonly referred to as Highway 400, historically as the Toronto–Barrie Highway, and colloquially as the 400, is a 400-series highway in the Canadian province of Ontario linking the city of Toronto in the urban and agricultural south of the province with the scenic and sparsely populated central and northern regions. The portion of the highway between Toronto and Lake Simcoe roughly traces the route of the Toronto Carrying-Place Trail, a historic trail between the Lower and Upper Great Lakes. North of Highway 12, in combination with Highway 69, it forms a branch of the Trans-Canada Highway (TCH), the Georgian Bay Route, and is part of the highest-capacity route from southern Ontario to the Canadian West, via a connection with the mainline of the TCH in Sudbury. The highway also serves as the primary route from Toronto to southern Georgian Bay and Muskoka, areas collectively known as cottage country. The highway is patrolled by the Ontario Provincial Police and has a speed limit of 100 km/h (62 mph), except for the section south of Highway 401, where the speed limit is 80 km/h (50 mph) and the 60 km (37 mi) stretch between MacTier and Nobel, where the speed limit was raised to 110 km/h (68 mph) on April 22, 2022.
King's Highway 403, or simply Highway 403, is a 400-series highway in the Canadian province of Ontario that travels between Woodstock and Mississauga, branching off from and reuniting with Highway 401 at both ends and travelling south of it through Hamilton and Mississauga. It is concurrent with the Queen Elizabeth Way (QEW) for 22 km (14 mi) from Burlington to Oakville. The Highway 403 designation was first applied in 1963 to a short stub of freeway branching off the QEW at Burlington, and the entire route was completed on August 15, 1997, when the section from Brantford to the then-still independent Town of Ancaster was opened to traffic. The section of Highway 403 between Woodstock and Burlington was formally dedicated as the Alexander Graham Bell Parkway on April 27, 2016, in honour of Alexander Graham Bell.
King's Highway 410, also known as Highway 410 and colloquially as the four-ten, is a 400-series highway in the Canadian province of Ontario that connects Highways 401 and 403 to Brampton. North of Brampton, the commuter freeway ends and the route becomes Highway 10, which continues north through Caledon as a four-lane undivided highway. The route is patrolled by the Ontario Provincial Police and has a speed limit of 100 km/h (62 mph).
King's Highway 416, commonly referred to as Highway 416 and as the Veterans Memorial Highway, is a 400-series highway in the Canadian province of Ontario that connects Highway 417 in Ottawa with Highway 401 between Brockville and Cornwall. The 76.4-kilometre-long (47.5 mi) freeway acts as an important trade corridor from Interstate 81 between New York and Eastern Ontario via Highway 401, as well as the fastest link between Ottawa and Toronto. Highway 416 passes through a largely rural area, except near its northern terminus where it enters the suburbs of Ottawa. The freeway also serves several communities along its length, notably Spencerville and Kemptville.
The Hanlon Expressway or Hanlon Parkway is a limited controlled-access expressway connecting Highway 401 with the city of Guelph in the Canadian province of Ontario. The 17 km (11 mi) route travels in a generally north–south direction on the city's west side. It is signed as Highway 6 for its entire length; from Wellington Street to Woodlawn Road it is concurrent with Highway 7. The speed limit alternates between 70 and 80 km/h.
King's Highway 6, commonly referred to as Highway 6, is a provincially maintained highway in the Canadian province of Ontario. It crosses a distance of 480 km (300 mi) between Port Dover, on the northern shore of Lake Erie, and Espanola, on the northern shore of Lake Huron, before ending at the Trans-Canada Highway (Highway 17) in McKerrow.
Black Creek Drive is a limited-access arterial road in Toronto, Ontario, Canada. A four-lane route that runs north–south, it connects Weston Road and Humber Boulevard with Highway 401 via Highway 400, the latter of which it forms a southerly extension. Black Creek Drive officially transitions into Highway 400 at the Maple Leaf Drive overpass, southeast of the Jane Street interchange. The roadway is named after the Black Creek ravine, which it parallels for most of its route. It features a maximum speed limit of 70 km/h (43 mph).
The Veterans Memorial Parkway is a 13.4 km limited-access and municipally maintained parkway located entirely within London, Ontario. The parkway was previously the provincial King's Highway 100 from 1977 until 1993, and was formerly named Airport Road from 1977 to September 2006. It begins in the south at Wilton Grove Road and ends at Clarke Road, which it continues as northward.
King's Highway 85, commonly referred to as Highway 85, is a provincially maintained highway in the Canadian province of Ontario, connecting Highway 7 to immediately north of the Waterloo city limits. The 10-kilometre (6.2 mi) highway, which is mostly controlled-access, travels through the Regional Municipality of Waterloo along the Conestoga Parkway from its interchange with Highway 7, which continues south along the parkway, to an interchange with Regional Road 15, where it continues as Regional Road 85 to St. Jacobs.
King's Highway 413, known as the GTA West Corridor or GTA West until 2021, is a planned 400-series highway and bus transitway in the western Greater Toronto Area of the Canadian province of Ontario. The approximately 52-kilometre (32 mi) route is currently undergoing planning and analysis under an environmental impact assessment (EA) by the Ministry of Transportation of Ontario (MTO) and the Government of Ontario. If approved, a new four-to-six lane controlled-access highway would be built between the existing interchange of Highway 401 and the 407 ETR at the Halton–Peel boundary, and Highway 400 north of Vaughan. In addition, two new extensions would be built to connect Highway 410 and Highway 427 with Highway 413.
