Bridge Documentation

With its relatively late 1970 construction date, this bridge pales in significance next to the famous Pont de Québec it parallels, however it is notable as the longest suspension span in Canada. Its span is longer than the Pont de Québec because Pont de Québec has one of its its main piers in the water, while this bridge has both its tower piers on the shore. One interesting features of the towers is that the foundations are faced in stone. Use of stone is rather unusual by the 1960s and 1970s.

The total length of this bridge is reported in Wikipedia as 1,041m (3,414 ft) between anchorages however approach spans extend beyond the anchorages at the south end. The total length given by HistoricBridges.org is an estimate taking this approach into account.
