Hwy. 401 express lanes close for a week in Mississauga


Published June 19, 2023 at 9:40 am

The express lanes on a section of Hwy. 401 in west Mississauga will completely shut down to traffic for a full week starting this Wednesday morning (June 21).

The eastbound express lanes of the major highway between Winston Churchill Blvd. and the Credit River (Creditview Rd.) will close to traffic from this Wednesday at 5 a.m. until the following Wednesday (June 28) at 5 a.m., project leaders overseeing the Hwy. 401 expansion say.

Officials with West Corridor Constructors, contractor on the $640-million Hwy. 401 Expansion Project, warn drivers to expect significant delays in the area while the express lanes are closed.

The collector lanes will remain open to traffic, officials add.

“The closure is required to facilitate construction activities as part of remaining seasonal works. Motorists are advised to
follow posted construction signage, drive with caution and according to road conditions and posted speed limits,” project leaders said in an online notice of the lane closures.

Or, officials add, people can plan alternate routes.

While work on the westbound lanes on the same stretch of Hwy. 401 was completed last fall, work continues on the eastbound lanes.

After some two years of heavy traffic delays in the area, the westbound express lanes were extended as of last November from west of Mavis Rd. to Winston Churchill Blvd.

The extension, which provided westbound Hwy. 401 a full express and collector system across Mississauga with the exception of a small stretch of highway between Winston Churchill Blvd. and Hwy. 407, is part of the massive Hwy. 401 expansion project.

The undertaking began construction in 2019 and includes the widening of 18 kilometres of Hwy. 401 from Mississauga to Milton. 

Meanwhile, some work continues on the eastbound express lanes of Hwy. 401 in the same area.

The huge expansion project also includes reconstruction of bridges as well as upgrades to support facilities and features. 

Once completed, the Ontario government says the expanded highway will include: 

  • 12-lane core-collector system from the Credit River to Winston Churchill Blvd. 
  • 10 lanes from Winston Churchill Blvd. to Hwy. 407 ETR/ Hwy. 401 interchange 
  • 12-lane core-collector system from Hwy. 407 ETR/ Hwy. 401 interchange to James Snow Pkwy. 
  • 10 lanes from James Snow Pkwy. to RR 25 
  • median High Occupancy Vehicle (HOV) lanes 
  • new or improved support facilities and features, such as drainage, lighting, signage and carpool lots 

West Corridor Constructors was awarded the contract to design, build and finance the Hwy. 401 expansion project. 

Some 250,000 vehicles travel on Hwy. 401 in Peel and Halton each day.
