The widening of this bridge and Galipeault Bridge in 1964, both of them from two lanes to four, was done in a bid to appease Perrot Island residents and merchants, who were worried that the construction of nearby Île aux Tourtes Bridge, which provides a way around the island, would hurt their businesses.[2] A medium-size shopping mall, Le Faubourg de l'Île, was built next to the bridge on the Pincourt side, at the Cardinal Léger exit.
Like Galipeault Bridge, which it continues, Taschereau Bridge was built next to a Grand Trunk Railroad bridge that was built in 1854, and was the first fixed link between Montreal and the mainland.[2] The bridge was named after Louis-Alexandre Taschereau, who was Premier of Quebec at the time of its inauguration.
