Pont Monseigneur-Langlois, Road bridge in Coteau-du-Lac, Canada

The Monseigneur-Langlois Bridge is a steel structure that spans over 2 kilometers, connecting Salaberry-de-Valleyfield with Coteau-du-Lac. It crosses the Saint Lawrence River and the Soulanges Canal in four separate sections.

The bridge is named after Joseph-Alfred Langlois, bishop of the Diocese of Valleyfield from 1926 to 1966. Its four sections cross the Saint Lawrence River and the Soulanges Canal between Salaberry-de-Valleyfield and Coteau-du-Lac, linking the Vaudreuil-Soulanges and Beauharnois-Salaberry regional county municipalities in the Montérégie. The sources consulted give no construction or renovation dates.

The bridge carries the name of Joseph-Alfred Langlois, a bishop who led the Valleyfield diocese during the mid-1900s. This name reflects the importance of religious figures in the area's local identity.

The bridge carries Route 201 with four traffic lanes and is used by approximately 35,000 vehicles daily. It connects to Route 338 and Highway 20, so expect occasional traffic during busy hours.

The structure consists of four separate spans, with the longest section measuring about 425 meters between Aloigny Island and Liénard Island. This multi-span design allows it to cross the river's complex geography with multiple water bodies.
