This is a list of highways maintained by the government of Quebec.
The Autoroute system in Quebec is a network of expressways which operate under the same principle of controlled access as the Interstate Highway System in the United States or the 400-Series Highways in neighbouring Ontario.
Route de la Baie James (James Bay Road)
Route du Nord (North Road)
