This unique bridge is the work of Montreal engineers Beaulieu, Trudeau et associés, whose expertise was recognized in the 1966 Design Canada competition.
The history of Dominion Bridge is tied in with the building of the railway across Canada in the latter half of the nineteenth century. At that time, the company was in charge of erecting all of the railway bridges used by the Canadian Pacific Railway line between Montreal and Vancouver. Its steel expertise is evident in a number of imposing structures, some of which have symbolic value today. They include the Québec Bridge and the Jacques Cartier Bridge, the structural work in the Château Frontenac and the Champlain Bridge, and the cross on Mount Royal.
