Taschereau Bridge is a bridge linking Pincourt, on Île Perrot, to Vaudreuil-Dorion, in the Vaudreuil-Soulanges RMC across the West Channel of the Ottawa River. The bridge was originally built in 1925, and was doubled in 1964, as part of the same project as Galipeault Bridge, which links the island to Montreal Island, but it has been maintained independently since then. Both bridges carry four lanes of Quebec Autoroute 20, which becomes Harwood Boulevard on the Dorion side. However, Transports Québec plans to build a bypass between the bridge and the junction of Autoroute 540 and upgrade the highway on Île Perrot to freeway standards.
