New Samuel De Champlain Bridge Corridor

Maintenance of traffic and impact management: the importance of strong coordination

This mobility management mandate involved coordinating construction phasing, conducting traffic studies, and designing tailored mitigation measures, namely alternate routes and detour itineraries. Intervia also handled liaison and coordination with neighbouring major works (the Turcot Interchange, Bonaventure Expressway, and the REM to plan effective traffic-maintenance measures. In this capacity, Intervia chaired the Coordination and Impact Management Committee, where each planned obstruction was presented and discussed with all stakeholders, including MTQ and Infrastructure Canada.

In parallel, Intervia served as the primary point of contact with the good-neighbour committee for residents of Verdun and Nuns’ Island, who were most directly affected by the work. On the ground, our team also oversaw the implementation of mitigation measures, particularly signage.

Challenges of a large-scale project

Coordinating traffic maintenance on a worksite of this scale while concentrating very high traffic volumes in dense urban areas is both a technical and human challenge. For each construction phase, our team produced comprehensive, detailed traffic-maintenance scenarios and successfully adapted them on extremely tight timelines in response to unforeseen issues on site or at adjacent projects.

In Verdun and on Nun's Island, residents were regularly engaged to share the measures planned for each phase and to refine them based on their feedback and concerns covering motorists, cyclists, and pedestrians, including access to the multi-use path. Finally, we established close collaboration with public transit operators to maintain downtown access for South Shore residents. A dedicated transit corridor was implemented during construction to meet this objective, which is critical to mobility across Greater Montréal.
