The highway network connects all regions and neighbouring provinces, and is concentrated mainly around the major urban areas of Montreal and Quebec City.

The rest of the roadways are mostly managed by companies such as Hydro-Quebec or by various departments, such as the Ministère de l'Énergie et des Ressources naturelles (Ministry of Energy and Natural Resources (Quebec)).

To serve the vast territory of Quebec, the MTQ manages a network of more than 20,000 kilometers of roads, mainly in the south of the province.

The Autoroute (freeway) 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.

As the Trans-Canada Highway lacks a national numeric designation in the province, the signs are numberless (as shown below).

[1] For example, highway 105, 155 and 195 are respectively located in Outaouais (west), Mauricie (centre) and Bas-St-Laurent (east).

Its location (surrounded by a loop road) or its proximity to routes 195, 197, and 299 could explain its numbering.

Local roads link rural centres and properties together and each municipality has its own way of identifying streets.

These developments often take the form of creating a bicycle path along unpaved or reduced width roadways.

The lane markings along the roadway include a continuous white line along each side of the road's outside edge.
