Duplessis Bridge

Duplessis Bridge is a steel structure spanning the Saint-Maurice River in Trois-Rivières and connecting two sections of the city. The bridge stretches approximately 405 meters and accommodates both pedestrian and vehicle traffic across the water.

The original bridge collapsed in 1951 during extreme cold weather, resulting in multiple fatalities due to structural weaknesses. Investigations showed the construction had used poor-quality steel with elevated carbon content.

The bridge bears the name of Maurice Duplessis, a former Premier of Quebec who maintained substantial influence in the region's development.

The bridge is open to both pedestrians and vehicles with clear pathways for safe passage. Access is straightforward and does not require special arrangements to cross.

Investigations following the 1951 collapse revealed that the bridge's initial failure stemmed from the use of rimmed steel containing high carbon levels.
