Autoroute 15 (also called the DĂ©carie Expressway (English) or Autoroute DĂ©carie (French) between the Turcot and DĂ©carie 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 and extends via Montreal to Sainte-Agathe-des-Monts with an eventual continuation beyond Mont-Tremblant. The total length of A-15 is currently 164 km (101.9 mi), including short concurrency (4 km or 2.5 mi) with Autoroute 40 (Boulevard/Autoroute MĂ©tropolitan) that connects the two main sections. This is one of the few autoroutes in Quebec that does not have any spinoff highways.
Road descriptionâ»
Southern sectionâ»
![](https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Montreal_autoroute.jpg/250px-Montreal_autoroute.jpg)
The southern section of A-15 connects the south shore suburbs of Montreal and is also the primary trade corridor route between Montreal and New York City linking Quebec Autoroute 15 to Interstate 87 at the Canada-United States border at the Champlain-St. Bernard de Lacolle Border Crossing. This was the former Route 9, and connected with US 9 on the western shore of Lake Champlain. In Brossard, it joins up with A-10 and A-20 across the Champlain Bridge into Montreal. The A-10 splits off almost immediately after crossing the bridge to head into downtown Montreal at the Bonaventure Expressway and the A-20 splits off shortly after at the Turcot Interchange (Ă©changeur Turcot), leaving the A-15 to continue northward as Autoroute DĂ©carie until the DĂ©carie Interchange (Ă©changeur DĂ©carie) with the A-40 at the point where it turns from the Trans-Canada into the Metropolitan Expressway.
The route is also connected to Autoroute 30 in Candiac which was completed to Autoroute 20 in 2012 providing quick access to the south shore of Montreal, to southern communities located alongside Autoroute 15 and to the CanadaâUS border in Lacolle. It will also give quicker access from there to areas west of Montreal and also Ottawa and Gatineau.
DĂ©carie Autorouteâ»
![](https://upload.wikimedia.org/wikipedia/commons/thumb/b/b2/Autoroute_D%C3%A9carie.jpg/300px-Autoroute_D%C3%A9carie.jpg)
The DĂ©carie Autoroute is a sunken highway between the northbound and southbound lanes of Decarie Boulevard from the Metropolitan Autoroute at its northern end to Monkland Avenue and the Villa Maria Metro station at its southern end. It was built on a wide expanse of vacant land, donated to the city by the DĂ©carie estate on the condition that a streetcar line would be established. The decommissioning of the streetcar system in 1959 left the right-of-way as an obvious choice for a highway and so the DĂ©carie Autoroute was dug there. South of Queen Mary Road, however, were a significant number of houses that were demolished.
To avoid demolishing Notre-Dame-de-GrĂące Church, the highway makes a slight westerly jog below CĂŽte-Saint-Luc Road and runs through a short tunnel, before emerging between Addington and Botrel Streets and running down to Sherbrooke Street and Saint Jacques Street, where it spectacularly goes from being below the ground to well above the ground as it intersects with Autoroute 20 and Route 136 in the infamous Turcot Interchange (dubbed "Spaghetti Junction" by train crews operating the former CN Rail Turcot Yard). Following the conversion from streetcar line to the highway, the DĂ©carie estate sued the city. But was unable to prevail. Because it did not document its case well enough for the nevertheless sympathetic court.
DĂ©carie Boulevardâ»
DĂ©carie Boulevard itself continues; from Monkland Avenue south to Saint Jacques Street past the McGill University Health Centre Glen Campus superhospital; and from Autoroute 40 north into Montreal past Du College Station and CĂŽte-Vertu Station/Norgate shopping centre to Poirier Street. Between Monkland Avenue and A 40, DĂ©carie Boulevard serves as sort of a service road on both sides of the autoroute.
Northern sectionâ»
After its concurrency with A-40, the northern section of A-15 is the main highway route to the Laurentians or Laurentides, until it downgrades to Route 117. It also links up to the northern suburbs of Montreal, as well as provides a connection to the A-440, A-640 and the A-50 in Mirabel. The first section from A-40 to Saint-JérÎme was opened on August 29, 1959 (source Montreal Star Aug. 29, 1959, page 3) as a toll road, although the tolls were removed in 1985. This section was also the first to be designed as an autoroute in the province. It was named Autoroute Montréal-Laurentides during the 1960s.
Over the next years, it was extended north to Sainte-Agathe-des-Monts as a new connection to touristic and skiing destinations in the Laurentides including in Saint-Sauveur, Sainte-AdÚle and Estérel. In the future, it is possible that the A-15 may continue even farther north, past Mont-Tremblant, as Route 117 is already an at-grade expressway with a freeway bypass of Mont-Tremblant 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 were a different route. The northern route is also part of the Trans-Canada Highway.

Disastersâ»
On February 19, 2020, white-out conditions caused a pile-up involving more than 200 vehicles in La Prairie, a suburb of Montreal. Two persons died and "more than 70 were injured."
On June 18, 2000, the southern portion of the Boulevard du Souvenir overpass in Laval (which crosses over Quebec Autoroute 15), under reconstruction, collapsed into the roadway, killing one and injuring two when cars were crushed underneath the structure. Sixteen beams weighing about 70 tonnes (69 long tons; 77 short tons) each fell. The contractor was faulted for shoddy work. The arched concrete beams were unsecured and tipped over like dominoes, many of them breaking into pieces.
The expressway has also seen flooding. On July 14, 1987, a sudden torrential downpour caused by an HP supercell thunderstorm dumped over 100 millimetres (3.9 inches) of rain in just over one hour across the city. The DĂ©carie Expressway, which is below-grade, was heavily flooded and became a river. At some locations, the water reached a maximum of 3.6 metres (12 feet) in depth on the roadway. Over 300 vehicles were abandoned when they were submerged. Two people were killed by the storm. One 80-year-old man on the Expressway drowned and another one was killed by electrical wires (electrocuted). On July 5, 2005, another torrential downpour flooded portions of the Expressway after several manhole covers blew open from the storm sewers below them being overloaded.
