Maintenance of Traffic and Impact Management: The Importance of Good Coordination

This mobility management project consisted of coordinating the phasing of the work, conducting traffic studies, and designing appropriate mitigation measures, i.e. alternate and detour routes. Intervia also liaised and coordinated with those responsible for major neighbouring construction sites (Turcot Interchange, Bonaventure Expressway, REM) to plan effective traffic maintenance measures. In this capacity, Intervia chaired the coordination and impact management committee, where each obstacle was presented and discussed with all stakeholders such as the MTQ or Infrastructure Canada.

At the same time, Intervia acted as the main contact with the Good Neighbour Committee of the residents of Verdun and Nuns' Island, who were the most directly impacted by the work.

Finally, in the field, our team monitored the implementation of mitigation measures, including signage.

Challenges and issues of a large-scale project

Coordinating maintenance of traffic on a construction site of this magnitude with very high traffic volumes in an urbanized area is both a technical and human challenge. For each phase of the work, our team produced complete and detailed traffic maintenance scenarios and was able to adapt them within extremely tight deadlines in the face of unforeseen events on the construction site or at the sites of neighbouring projects.

In Verdun and Île-des-Sœurs, residents were met regularly to inform them of the measures planned for each phase and to make corrections in light of their recommendations and concerns, aimed at motorists, cyclists and pedestrians, including their access to the multipurpose path. Finally, close collaboration was established with public transit operators to maintain accessibility to the downtown core for South Shore residents. A public transit corridor was set up during the work to meet this crucial objective for Greater Montréal's mobility.
