As our first major bridge project, this concrete and steel bridge over the Massawippi River, at the south limit of Lennoxville, Quebec, established the foundation for our continuously growing bridge practice.

Spanning 550 feet over the Saint-François River in Sherbrooke, this new bridge stood as one of the longest reinforced concrete bridges in Quebec. Use of this material was an innovation in Canada at the time and a testament to the power of progress through design.

To address significant development within Sherbrooke, Quebec, we proposed a new steel and reinforced concrete structure over the Magog River. The bridge opened in 1954.
