Grand-Mère Bridge

The Grand-Mère Bridge is a steel suspension bridge spanning roughly 289 meters across the Saint-Maurice River connecting Shawinigan. Thick steel cables suspend the deck from tall towers anchored on both riverbanks, creating the distinctive shape of a suspension structure.

Construction finished in 1929 under the Canadian Bridge Company and it was the longest suspension bridge in Canada at that time. This achievement demonstrated the growing capability of North American engineers to build complex structures across wide waterways.

The bridge has shaped Shawinigan's character for generations and connects the two riverbanks in a way that locals depend on daily. It serves as a symbol of unity between the districts and remains part of the region's identity.

The bridge sits on route QC-153 and allows vehicles and pedestrians to cross the river between districts. The best view of the structure comes from river level or the banks, especially during daylight when the steel framework is clearly visible.

The main cables are made from thick steel strands, each composed of 35 individual wires, which represented a new level of technical precision when completed. This construction method made it a reference project for future suspension bridges.
