Turcot interchange project takes home major award.
WSP was well-represented at the ACEC Quebec’s recent engineering excellence gala with six nominations and a major award.
For 19 years these awards, presented by the Association of Consulting Engineering Companies of Quebec (ACEC), have highlighted innovation in the engineering sector.
At the annual ACEC gala, held on May 27 at the Grande Bibliothèque in Montreal, teams from several different sectors came together to proudly represent WSP.

Léonard Award for the Turcot project
The Turcot project is currently the most complex road work zone in North America in terms of the order of execution of work. This project also features several innovations, which is one of the numerous reasons this project earned this prestigious honour.
The project’s greatest challenge is maintaining mobility for the 300,000 vehicles that use the Turcot Interchange every day. This key obligation is central to how the project is planned and managed.
Taking existing ramps out of service implies that new ramps will be needed. However, few of the new ramps could be built without first demolishing the existing ones to free up space.
The existing ramps cannot be demolished without opening a new roadway link to replace them. To solve this challenge, throughout all of 2017 and 2018, numerous temporary structures were built and used to divert traffic. Thirty-five temporary structures were required — or nearly 12 km of temporary lanes —to take the existing interchange out of service.
Sustainable development is a top priority
The work sequence enables alternating between dismantling existing structures and building new ones. This cycle makes it possible to support reuse of materials and reduce waste of resources. On the job site, more than 90 per cent of the concrete from demolished structures is ground down to be reused in the capping layer of new structures.
A future ready project
The finished interchange will be suited to the current and future realities of transportation and will include lanes reserved for buses and carpooling. In a municipal environment, non-polluting modes of transport like biking and walking will be promoted with the addition of bike lanes and new pedestrian links.
