The Québec Bridge is the longest span cantilever bridge in the world, stretching 548.6 meters between the main piers. Completed in 1917, it was a remarkable engineering achievement. To overcome technical problems that had caused the collapse of an earlier span and the loss of 76 lives in 1907, Canadian engineers used nickel steel as a structural material and an innovative K-truss design. Designed and built by the St. Lawrence Bridge Company of Montréal, this impressive work is universally recognized as a symbol of engineering excellence.
