Pont Viau (Viau Bridge), also called Ahuntsic Bridge (1930, rebuilt 1962 and widened 1993) .
This bridge spans the Rivière des Prairies between the Montreal borough of Ahuntsic-Cartierville and the Laval (Île Jésus) neighbourhood of Pont-Viau. It is part of Route 335. About 36 000 motorists each weekday cross the bridge. The Société de transport de Laval, has a designated bus lane for one of its bus routes heading south towards Henri-Bourassa Terminus Nord and the Henri Bourassa Station and north towards Cartier Station. The Line 2 Orange of the Montreal Metro that was extended in 2007 northward to Laval is backed up with the bus route of the same number (2). On August 8, 2007, a large hole and crack in the bus-only lane near the Boulevard des Laurentides (Laval) side of the bridge brought the complete closure, but an inspection concluded that the bridge had no structural problems or damage and was reopened during the same day .
A wooden bridge was built there in 1847.
