The Quebec Bridge is a road, rail, and pedestrian bridge across the lower Saint Lawrence River between Sainte-Foy and Lévis, in Quebec, Canada. The project failed twice during its construction, in 1907 and 1916, at the cost of 88 lives and additional people injured. The bridge eventually opened in 1919.
