Quebec Bridge

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 persons injured. It took more than 30 years to complete and eventually opened in 1919.

The Quebec Bridge is a riveted steel truss structure and is 987 m long, 29 m wide, and 104 m high. Cantilever arms 177 m long support a 195 m central structure, for a total span of 549 m, still the longest cantilever bridge span in the world. It is the easternmost complete crossing of the Saint Lawrence River.
