The main route spans 7,476 km (4,645 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 Quebec Autoroute System or le système d'autoroute au Québec 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 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.

The total length of A-15 is currently 164 km (101.9 mi), including a short concurrency with Autoroute 40 that connects the two main sections. This is one of the few autoroutes in Quebec that does not have any spinoff highways.

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.

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.
