Bridge Documentation

This massive bridge is the only bridge in between Montréal and Québec City. Because it is the only crossing between those two points, it is a very busy bridge. The main three spans appear to be configured as cantilever trusses which extend over the navigation channel to hold a tied arch suspended span. Evidence of this appears to be confirmed by the presence of hinges (pin connections) where the cantilever arms end and the suspended tied arch span begins. The bridge may be one of the largest bridges of this design in North America.

In addition to the main spans, there is an extremely long approach system. Over the river, through truss spans are present. Some of these spans appear to be configured as cantilevers, again evidenced by the presence of hinges/pin connections at bottom chord connections at certain points. Approach spans over land are deck plate girder spans, and they too appear to cantilever slightly. These spans have evidence of cantilever design because the bearings are positioned a short distance from the pier points. The girder spans actually rest on top of each other, with bearing points being in the middle of the girders.

On September 7, 1965, during construction, a caisson failed due to water pressure, killing 12 workers. Dominion Bridge was the contractor for the bridge. Other contractors included Simard et Beaudry, MacNamara Québec, and Dufresne Engineering. The tallest point of the bridge structure is 350 feet, and the highest point of the deck is 180 feet.
