The Deconstruction of the Champlain Bridge

A four-year collaboration.

Bridge deconstruction

Once spanning 3.4 km, the Champlain Bridge, one of North America’s busiest bridges, with 50 million vehicles crossing it each year, previously stood in a delicate environment where the river, its flora and fauna, and protected species such as the falcon and the white-fronted swallow coexisted.  

Today, the original infrastructure no longer exists. The deconstruction, conducted by the Jacques Cartier and Champlain Bridges Incorporated (JCCBI) and the NHSL consortium (formed by Pomerleau and Delsan-A.I.M. Environmental Services), lasted between 2020 and 2023 and showcased Canadian expertise in complex and major bridge projects.  

The impactful Montreal-based project stands as a testament to sustainability, having reduced the site’s carbon footprint while safeguarding the delicate ecosystem of the St. Lawrence River.

"Our common mission was to minimize potential impacts on citizens, as well as on the wildlife and ecosystems present in and around the shores of the St. Lawrence. To this end, several environmental monitoring and verification programs were set up on the project site and in the communities. These measures made it possible to monitor the environmental compliance of activities and to share monitoring results with the public via the various digital platforms dedicated to the deconstruction project."- Simon Hébert, Civil Works Manager, Delsan-A.I.M.
