Each day more than 300,000 vehicles travel through Montreal's Turcot interchange, which connects Québec’s two busiest highways and enables travel to the Champlain Bridge, Pierre Elliott Trudeau International Airport, and downtown Montreal. The ministère des Transports du Québec (MTQ – Québec Ministry of Transportation) is replacing the 45-year-old interchange, which is showing its age. Tetra Tech and partner AECOM have participated in the management of this project since 2008.

The project affects a diverse urban area seven kilometers by three kilometers, crossing several administrative jurisdictions in Southwest Montreal. The project will completely replace four well-traveled interchanges and relocate lanes of Highway 20 and the nearby Canadian National Railway tracks.

The Tetra Tech team is providing professional support services in engineering and project management to achieve project objectives including ensuring the longevity of Turcot's new infrastructure, improving highway safety, and limiting effects on the surrounding area.

Services include:

  • Planning and cost control, including change management
  • Risk analysis
  • Project scheduling and documentation management
  • Technical content management, including developing a Work Breakdown Structure, monitoring and control tools, and managing technical aspects related to bridges and viaducts
  • Project integration, including project management manual and work plan
  • Developing a Quality Management Plan (ISO 9001), Quality Assurance, and Environmental Management Plan (ISO 14 001)
  • Supporting external communications, procurement activities, and real estate activities including right-of-way acquisition and liberation
  • Supporting the selection process for firms to complete the substructure components

This is a two-phase project, including a design-build phase specific to the main structural components. The full interchange replacement project is scheduled for completion in 2018.
