Designing and Building a New Bridge over the Historic Chambly Canal

This project consisted of designing and building a new bridge over the Chambly Canal as a replacement for bridge No. 9, which had reached the end of its useful life. The team had to tackle and resolve the complexities inherent in designing a new type of bridge in a very reduced space, while protecting the natural environment and maintaining navigation on the canal.

A Unique Swing and Moveable Bridge

We decided on a bascule bridge concept, in which movement is activated by means of hydraulic cylinders. The services we provided were the plans and specifications; work supervision; coordination; site monitoring; bridge engineering; hydraulics; instrumentation, automation and controls; road engineering; electrical engineering and 3D visual simulations.

The structure is 100% steel and was honoured at the Canadian Institute of Steel Construction’s 2012 awards for Quebec’s best steel projects. It will offer current and future generations an overview of the technical achievements associated with our era, while preserving the commemorative integrity of this historic site.
