Autoroute 15 (also called the
Décarie Expressway (English) or
Autoroute Décarie (French) between the
Turcot and
Décarie Interchanges in
Montreal and the
Laurentian Autoroute (English) or
Autoroute des Laurentides (French) north of
Autoroute 40) is a
highway in western
Quebec,
Canada. It was, until the extension of
Autoroute 25 was opened in 2011, the only constructed north-south autoroute to go out of Montreal on both sides. A-15 begins at the end of
Interstate 87 at the
United States border at
Saint-Bernard-de-Lacolle to
Sainte-Agathe-des-Monts with an eventual continuation beyond
Mont-Tremblant. The total length of A-15 is currently , including a short concurrency with Autoroute 40 (Boulevard/Autoroute Métropolitan) that connects the two main sections. This is one of the few autoroutes in Quebec that does not have any spinoff highways.
