Winning Bidder

The Windsor Essex Mobility Group (WEMG) is the consortium selected to design, build, finance and maintain the Parkway. WEMG is a partnership between ACS Infrastructure Canada Inc., Acciona Concessions Canada, and Fluor Canada Limited. 


  • The six-lane, 11 kilometre freeway and four-lane service road has 11 covered tunnels.
  • Tunnels range in size from 120 metres to 240 metres long, totaling 1.8 kilometres.
  • Extensive landscaping with more than 300 acres of green space and 17 kilometres of recreational trail.

Community And Green Benefits

  • Provides a freeway for commercial motorists and reduces heavy traffic in residential areas. (At the time of the project's construction, nearly one-third of all Canada-U.S road trade travelled through the Detroit-Windsor border and through residential neighbourhoods in Windsor-Essex);
  • Recreational trails connect communities and promote healthy living;
  • Green space was integrated with local parks and other protected natural areas to create a green corridor that supports viable natural communities and buffers surrounding communities from the freeway;
  • Species-at-risk and their habitats are protected for the long-term, and where necessary, they were relocated to areas that were restored, enhanced or created and protected.

Economic Benefits

  • The project was a major catalyst for job creation, other public projects and partnerships.
  • The project's primary contractor, Parkway Infrastructure Contractors (PIC), partnered with Ontario-based companies to construct the project. 
  • PIC estimates that between 60 to 80 sub-contracts worth hundreds of millions of dollars were put out to tender over the course of the project.
  • Much of the Parkway's construction and maintenance work were performed by local sub-trades and the majority of on-site labour went to tradespeople in the region.
  • About 1,200 workers were on the site daily, at the peak of construction. 
  • WEMG estimates its partners spent hundreds of millions of dollars on local labour, local supplies, and materials over the lifespan of the project.
