Built in the heart of downtown, the Dufferin-Montmorency Highway bears the names of Charles de Montmorency, French admiral on Samuel de Champlain’s expedition in 1603, and Lord Dufferin, who served as governor-general of Canada from 1872 to 1878. The construction of these interchanges in the 1960s and 1970s required the demolition of several buildings in Saint-Roch, one of the oldest districts in Québec City.
