The Trans-Canada Highway 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 7,821 km (4,860 mi) across the country, one of the longest routes of its type in the world. 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.
The autoroute system is a network of freeways within the province of Quebec, Canada, operating under the same principle of controlled access as the Interstate Highway System in the United States and the 400-series highways in neighbouring Ontario. The Autoroutes are the backbone of Quebec's highway system, spanning almost 2,400 km (1,491 mi). The speed limit on the Autoroutes is generally 100 km/h (62 mph) in rural areas and 70–90 km/h (43–56 mph) in urban areas; most roads are made of asphalt concrete.
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 25 is an Autoroute in the Lanaudière region of Quebec. It is currently 49 km (30.4 mi) long and services the direct north of Montreal's Metropolitan Area. The A-25 has one toll bridge, which is the first modern toll in MMA and one of two overall in Quebec.
Route 132 is the longest highway in Quebec. It follows the south shore of the Saint Lawrence River from the border with the state of New York in the hamlet of Dundee, west of Montreal to the Gulf of Saint Lawrence and circles the Gaspé Peninsula. This highway is known as the Navigator's Route. It passes through the Montérégie, Centre-du-Québec, Chaudière-Appalaches, Bas-Saint-Laurent and Gaspésie regions of the province.
Route 138 is a major highway in the Canadian province of Quebec, following the entire north shore of the Saint Lawrence River past Montreal to the temporary eastern terminus in Kegashka on the Gulf of Saint Lawrence. The western terminus is in Elgin, at the border with New York State south-west of Montreal. Part of this highway is known as the Chemin du Roy, or King's Highway, which is one of the oldest highways in Canada.
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 kilometers 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.
Route 136 (R-136), known as the Ville-Marie Expressway (English) or Autoroute Ville-Marie (French) is an Autoroute highway in the Canadian province of Quebec that is a spur route of Autoroute 20 in Montreal. Its western terminus is located at the Turcot Interchange, a junction with Autoroute 15 and Autoroute 20, and its eastern terminus is near the Jacques Cartier Bridge, where the highway merges with Notre-Dame Street. The Autoroute Ville-Marie designation is named after the downtown borough of Ville-Marie, through which the expressway is routed.
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 at 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.
Route 116 is an east/west highway on the south shore of the Saint Lawrence River in Quebec, Canada. Until the mid-1970s it was known as Route 9. Its eastern terminus is in Lévis at the junction of Route 132, and the western terminus is at the junction of Route 134 in Lemoyne part of a concurrency with Route 112 until Saint-Hubert just south of the Saint-Hubert Municipal Airport. The stretch between Lévis and Plessisville does not have much traffic, since Autoroute 20 is not that far from the highway. Between Plessisville and Richmond traffic is heavier as it passes bigger towns, and it is further away from Autoroute 20. From Richmond to Autoroute 20, it is quiet again, before reaching Saint-Hyacinthe, where it becomes a busy four-lane separated highway, going through the growing "South Shore" suburbs of Montreal. From the junction of Autoroute 30 to its western terminus, it is a controlled-access Autoroute-grade expressway. This portion was once envisioned to be part of Autoroute 16. An unofficial extension of Route 116 as thought of by locals, from the western terminus follows the Route 134 limited access expressway to the Jacques Cartier Bridge.
Route 112 is a busy east/west highway on the south shore of the Saint Lawrence River in Quebec, Canada. Its eastern terminus is in Frampton at the junction of Route 275, and the western terminus is in Downtown Montreal, after crossing the Victoria Bridge. The stretch between Vallée-Jonction and Sherbrooke is a very busy highway as it is the main link between the southern regions of Quebec, in particular the Beauce region and the Eastern Townships. Between Sherbrooke and Marieville there is less traffic, since Autoroute 10 is in close proximity to the highway. From Marieville to Montreal it is a very busy highway, in most parts a four-lane separated highway, upgraded to freeway standards in certain places.
Route 175 is a major north–south highway on both sides of the St. Lawrence River in Quebec, Canada. Its southern terminus is in Saint-Lambert-de-Lauzon at the junction of Route 218 and its northern terminus is in Saguenay at the junction of Route 172, in the former city of Chicoutimi. Route 175 crosses the Saint Lawrence River on the Quebec Bridge, and a little further north of downtown Quebec City, it merges with Autoroute 73 for about 30 km before continuing through the Laurentides Wildlife Reserve as a two-lane divided highway in Stoneham.
Route 158 is an east-west arterial road running between Lachute and Berthierville, north of the Ottawa and Saint Lawrence rivers, in the Laurentides region.
Route 247 is a north/south highway on the south shore of the Saint Lawrence River in the Estrie region of Quebec. Its northern terminus is in Magog at the junction of Route 112 and its southern terminus is in Stanstead, at the junction of Autoroute 55 less than 1 kilometre north of the Canada–United States border.
Route 335 is a north-south route from Montreal north into the Lanaudière region of Quebec.
Route 155 is a north/south highway on the north shore of the Saint Lawrence River in Quebec, Canada. Its northern terminus is in Chambord at the junction of Route 169, and the southern terminus is the Piles Bridge in Shawinigan. Previously the highway continued to Autoroute 20 but that section was decommissioned in 2006 when Autoroute 55 was completed.
Route 201 is a north/south provincial highway within the Canadian province of Quebec, running between Route 202 in Franklin and Route 342 in Rigaud. Its total length is approximately 70 kilometres.
The réseau routier québécois is managed by the Quebec Ministry of Transportation and consists of about 185,000 kilometres (115,000 mi) of highways and roads. In addition, Quebec has almost 12,000 bridges, tunnels, retaining walls, culverts, and other structures such as the Quebec Bridge, the Pierre Laporte Bridge, the Laviolette Bridge and the Louis-Hippolyte Lafontaine Bridge–Tunnel.
