TYLin, in a Joint Venture with IBC and SNC-Lavalin, served as the Managing Partner and Lead Designer for the Samuel De Champlain Bridge in Montréal, Québec, Canada.
Serving as a major gateway into the city, the 3.4-kilometre-long Samuel De Champlain Bridge is an asymmetric cable-stayed bridge with an iconic 170-metre-high concrete tower and stay cables in an aesthetic harp arrangement. The project included the approach spans and the cable-stayed portion crossing the navigational channel of the Saint Lawrence Seaway.
TYLin’s three-corridor design accommodates two three-lane corridors for vehicular traffic, a central transit corridor to carry a light-rail transit system, and a multi-use path for pedestrians and cyclists.
TYLin 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 for the replacement structure.
- The Samuel De Champlain Bridge is the cornerstone of the Government of Canada’s New Champlain Bridge Corridor Project, one of the largest infrastructure projects in North America.
- Along with fast-track schedule, the project included stringent design and performance criteria, including a service life of 125 years.
- Site challenges have included construction under severe winter conditions, wind and seismic hazards, strict navigational requirements, and construction in a densely developed urban center.
- To meet the numerous challenges, the project team utilized an innovative combination of largescale precasting, modular segments with post-tensioning, and creative erection sequencing.
