The Quebec Bridge (French: pont de Québec) is a road, rail, and pedestrian bridge across the lower Saint Lawrence River between Sainte-Foy (a former suburb that in 2002 became the arrondissement Sainte-Foy–Sillery–Cap-Rouge in Quebec City) 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.
The Quebec Bridge is a riveted steel truss structure and is 987 m (3,238 ft) long, 29 m (95 ft) wide, and 104 m (341 ft) high. Cantilever arms 177 m (581 ft) long support a 195 m (640 ft) central structure, for a total span of 549 m (1,801 ft), still the longest cantilever bridge span in the world. (It was the all-categories longest span in the world until the Ambassador Bridge was completed in 1929.) It is the easternmost (farthest downstream) complete crossing of the Saint Lawrence River.
