New Champlain Bridge Corridor Project: Design and Construction

As the majority shareholder of the Signature on the Saint-Lawrence Group (SSL) consortium, SNC-Lavalin has been tasked with the design, construction and maintenance of Montreal’s new Champlain Bridge as part of a public-private partnership agreement with the Government of Canada. With a 125-year design life, the new crossing will include a 3.4-kilometre bridge across the St. Lawrence River, as well as a 470-metre bridge connecting Montreal to Ile-des-Soeurs. In addition, the 4.5-kilometre federal portion of Highways 15 and 10 will be reconstructed and widened.

A functional structure and an exceptional landmark

The new Champlain Bridge will not only replace the current span, one of the busiest crossings in Canada with 60 million vehicles passing over it each year, but it will also become an iconic landmark in Montreal’s skyline. The new structure is designed to be a gateway into the city, with significant architectural input included in the project design criteria.

Esthetic lighting will be added on the main tower and bridge for a visually striking effect when night falls. Cyclists and pedestrians will be able to safely travel over the bridge on a multi-use path and stop at one of the four belvederes to gain an exceptional vantage point over the city.

A design built to last

Durability is also a key design consideration, with a 125-year service life specified by the public partner, Infrastructure Canada. In addition to high-performance materials, the bridge incorporates the modernized seismic design criteria of the Canadian Highway Bridge Design Code, and elements of the Eurocodes for the design of steel and concrete elements.

SNC-Lavalin is proud to be designing and building the new Champlain Bridge, which will contribute to quality of life in Montreal for generations to come. Our teams have also been tasked with the geotechnical and environmental aspects of the project.

"Bridges are among the most exciting infrastructure projects to build. It is a great privilege to be working on one of the projects that will change the city's urban landscape for many generations to come." — Hugh Boyd, Project Director for Signature on the Saint Lawrence.
