T.Y. Lin announces opening of Samuel De Champlain Bridge in Canada


Full-service infrastructure consulting firm T.Y. Lin International (TYLI) has announced the opening of the new Samuel De Champlain Bridge over the St. Lawrence River in Montréal, Québec, Canada.

TYLI and its joint venture partners International Bridge Technologies and SNC-Lavalin served as the managing partner and lead designer for the 3.4km-long replacement bridge, which spans the St. Lawrence River between the communities of Montreal and Brossard.

The project was the result of a public-private partnership between Infrastructure Canada and Signature on the St. Lawrence (SSL).

It comprises two traffic corridors with three lanes in each direction, a central corridor dedicated to public transit, the future Réseau express métropolitain train, and a multi-use path for cyclists and pedestrians.

The Samuel De Champlain Bridge was opened in two phases with the first phase involving the northern lanes toward Montréal on 24 June 2019, followed by the second phase involving the southern corridor toward Brossard opened on 1 July 2019.

Intended to replace the old Champlain Bridge which was opened to traffic in 1962, the Samuel De Champlain Bridge features three independent superstructures supported by common piers.

The superstructures include the 529m-long, asymmetric cable-stayed bridge signature span, with a main span of 240m; the 762m-long East Approach, with a maximum span of 109m; and the 2,044m-long West Approach, with a typical span of 80.4m.

TYLI senior vice-president and bridge line of business technical director Marwan Nader said: “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.”

Said to be the cornerstone of the Government of Canada’s New Champlain Bridge Corridor Project, the new bridge features a single, 170m-high concrete tower and stay cables in an aesthetic harp arrangement.
