Quebec Autoroute 15
Encyclopedia : Q : QU : QUE : Quebec Autoroute 15
Autoroute 15 (also called Autoroute Décarie in Montreal and Autoroute des Laurentides north of Autoroute 40) is an Autoroute in western Quebec. It is the only north-south Autoroute to go out of Montreal on both sides, running from the United States border at Saint-Bernard-de-Lacolle (where it continues as Interstate 87) to Sainte-Agathe-des-Monts with intentions to continue beyond Mont-Tremblant. The total length of A-15 is currently 164 km (102 miles), including a short multiplex with Autoroute 40 that connects the two main sections.
The southern section of A-15 connects the southern suburbs of Montreal and is also the primary trade corridor between New York and Montreal. In Longueuil, it joins up with A-10 and A-20 across the Champlain Bridge into Montreal. A-10 splits off almost immediately after crossing the bridge to head into downtown Montreal and A-20 splits off shortly after at a stack interchange, leaving A-15 to continue northward on the Décarie until the A-40 interchange.

The northern section of A-15 is the main freeway route to the Laurentians until it downgrades to Quebec route 117. It also links up to the northern suburbs of Montreal, as well as provides a connection to A-440 and A-50 in Mirabel. In the future, it is possible that A-15 may continue even farther north, past Mont-Tremblant, as Route 117 is already an at-grade expressway with a freeway bypass of Saint-Jovite completed, and the name Autoroute des Laurentides is also recognized on the freeway bypass (and exit numbers continue). This section is numbered separately from the southern section as if it was a different route. This is also part of the Trans-Canada Highway.
An art project, the Decarie Project, concerning the cultural groups flanking Autoroute 15 in its Montreal Decarie section was exhibited in 2005 at the Saidye Bronfman Centre * [link]
