Deconstruction of the Original Champlain Bridge

Our engineers and traffic management specialists were actively involved in the planning, coordination, implementation, and monitoring of the closures required to carry out the work efficiently and safely. For example, the complete temporary closure of four major roadways beneath the Champlain Bridge enabled the contractor to mobilize 32 specialized excavators to demolish four bridge spans and concrete piers on both sides of the R-132 expressway and its service roads, all completed within a single weekend!

To ensure seamless coordination among major construction projects across the Greater Montréal area, our team worked closely with multiple stakeholders, including JCCBI (the bridge owner), the Ministère des Transports et de la Mobilité durable (MTMD), the cities of Montréal and Brossard, nearby municipalities, and other major infrastructure players such as SSLC, NouvLR, and RLF.

The objective was to design and implement appropriate mitigation strategies to reduce inconvenience for both road users and nearby residents. These measures included the implementation of alternate routes to facilitate detours, the deployment of police officers at key locations, the scheduling of intensive weekend and night work blitz, maintaining residential access at all times, and the continuous dissemination of information to partners and citizens throughout the project.
