The Quebec Bridge collapses during construction, killing 76 people and injuring many more, including several Mohawk workers from Kahnawake. An investigation ensued, which caused a great stir in the media. The disaster was attributed to fundamental design flaws in the plans and to the stubbornness of the construction supervisor, who pushed the workers to continue work despite the structural problems they were pointing out to him.

Construction of the Québec Bridge

In the 19th century, Québec City became increasingly isolated without a link by rail to the southern shore of the St. Lawrence. Begun in 1900, construction of the Pont de Québec was completed on September 20, 1917. Two major collapses occurred, in 1907 and 1916, disrupting progress and killing 76 and 13 men, respectively. Initially open only to trains and pedestrians, a carriageway was added in 1929. At 549 metres, its cantilevered, cable-free central span was the longest in the world. This bridge is still considered a masterpiece of modern engineering. How well do you know this bridge?
