T.Y. Lin International Announces New Samuel De Champlain Bridge Open to Traffic in Montréal, Québec, Canada

T.Y. Lin International (TYLI), a globally recognized, full-service infrastructure consulting firm, announces that the new Samuel De Champlain Bridge over the St. Lawrence River in Montréal, Québec, Canada, has opened to traffic. TYLI, in a Joint Venture with International Bridge Technologies and SNC-Lavalin, served as the Managing Partner and Lead Designer for the 3.4-kilometer-long replacement bridge. The Samuel De Champlain Bridge opened in two phases, with the northern lanes toward Montréal opened on June 24, 2019, and the southern corridor toward Brossard opened on July 1, 2019.

The new Samuel De Champlain Bridge spans the St. Lawrence River between Île des Soeurs and Montréal’s South Shore and is the cornerstone of the Government of Canada’s New Champlain Bridge Corridor Project, one of the largest infrastructure projects in North America. Designed as an asymmetric cable-stayed structure, the landmark bridge features a single, 170-meter-high concrete tower and stay cables in an aesthetic harp arrangement. The bridge carries two traffic corridors with three lanes in each direction, a central corridor dedicated to a future light-rail transit system, and a multi-use path for pedestrians and cyclists.

TYLI worked closely with Signature on the Saint Lawrence, the consortium that oversaw bridge design and construction, and its project partners to meet the aggressive design-build schedule. Along with stringent design and performance criteria, the project came with various site constraints and hazards. These included construction under Montréal’s severe winter conditions, wind and seismic hazards, navigational requirements, no-construction zones, construction in a densely developed urban center, and strict compliance to the architectural requirements of the project.

“T.Y. Lin International is proud to have served on this vitally important project for the Government and people of Canada,” said Marwan Nader, Ph.D., P.E., TYLI Senior Vice President, Technical Director - Bridge Line of Business, and Engineer of Record for the new Samuel De Champlain Bridge. “Our goal was to design a bridge that reflects the beauty and elegance of Montréal and its environs while withstanding the region’s harsh weather and environmental conditions. The final result is an iconic, well-engineered structure that will serve and enhance the local landscape for 125 years.”

Serving as a major gateway into the City of Montréal, the Samuel De Champlain Bridge comprises three independent superstructures supported by common piers. These include the 529-meter-long, asymmetric cable-stayed bridge signature span, with a main span of 240 meters; the 762-meter-long East Approach, with a maximum span of 109 meters; and the 2,044-meter-long West Approach, with a typical span of 80.4 meters.

The Samuel De Champlain Bridge replaces the old Champlain Bridge, which opened to traffic in 1962 and stood as one of Canada’s busiest crossings. The new bridge will carry approximately 50 million crossings each year, representing international trade valued at $20 billion.
