Tetra Tech, in partnership with AECOM, who supported the Québec Ministry of Transport (ministère des Transports du Québec) as an integrated team, marked the conclusion of one of Québec’s largest, most challenging infrastructure projects—the 13-year, CAD$3.67 billion Turcot Interchange and Railways Reconstruction Project.

The project covers three by seven kilometers across a dense and diverse urban area of Montréal. It included reconstructing four interchanges and three highway sections, moving the Canadian National Railway tracks, and adding new municipal infrastructure connections. The main challenges were to rebuild infrastructure in a confined area underneath or near existing structures in Canada’s busiest corridor, with more than 300,000 vehicles commuting daily. This was also the first carbon-neutral road infrastructure project for the Québec Ministry of Transport.

Tetra Tech’s Mathieu Ashby, Ing., M.Sc. A., lead transportation division manager in Québec, said, “I would like to highlight the commitment of every member of our major project management team as well as the quality of their work. The success of the Turcot project was made possible by the contribution of nearly 100 specialists.”

Tetra Tech staff cited this as a once-in-a-lifetime project in terms of challenges, complexity, and duration. Our project management team completed more than 268,000 hours of work and treated over 9,200 plans, 2,150 review procedures, 320 presentations, and hundreds of meetings with partners and residents. Our work included experts from 10 specialties: management and administration, cost management, documentation management, agreement and integration management, communications, engineering support, construction management, environmental management, quality management and auditing and property management.

In 2021 Tetra Tech received a Canadian Consulting Engineering (CCE) Award and a Québec Consulting Engineering Award for our contributions to the project’s success.

Congratulations to everyone involved!
