The project is located between boulevard Saint-Martin Est, in Laval, and boulevard Industriel, in Bois-des-Filion. It will be developed along the current axis of route335 and will extend over 11.8 kilometres. A dual carriageway urban freeway with three lanes in each direction, including dedicated transit lanes, will be constructed.
The project includes: construction of four new interchanges; redevelopment of the autoroute 640 and route 335 interchange; construction of a new bridge located east of the Athanase-David bridge; repair of the current Athanase-David bridge; redevelopment and extension of the multipurpose path for pedestrians, cyclists, and off-road vehicle users; reconfiguration of the service roads at near autoroute 440 and autoroute 19; and development of a bus terminal and park-and-ride facility.
