Autoroute 19, also known as Autoroute Papineau (Papineau Highway), is an autoroute in Quebec. It crosses the Rivière des Prairies via the Papineau-Leblanc Bridge, connecting the borough of Ahuntsic-Cartierville in Montreal and the Duvernay neighbourhood in Laval.
There are plans to widen Route 335 to four lanes, which would be a continuation of A-19 from Autoroute 440 to the Anathase-David Bridge, on Rivière des Mille Îles, and Bois-des-Filion to relieve congestion along that stretch. The lands reserved for the project were expropriated in 1973 in conjunction of a future extension of the A-19. In 2007 Transport Minister Julie Boulet gave the green light for studies in the area.
A super two highway exists in Bois-de-Filion, north of Route 344 and south of Autoroute 640, just north of Pont David, which runs on the Highway 19 right-of-way.
