Highway 401 Widening from East of McLaughlin Road to East of the Credit River

MTO Contract 2015-2018

Project Background

 

The Ministry of Transportation has completed the Detail Design and Environmental Assessment for the widening of Highway 401 from east of McLaughlin Road to east of the Credit River (approximately 4 km) in the City of Mississauga, Region of Peel.

 

The project includes:

  • Widening of Highway 401 from its current six-lanes to a twelve-lane core/collector system, including ten general purpose lanes and two high-occupancy vehicle lanes;
  • High-occupancy vehicle  lanes from west of Mavis Road to east of Highway 410 to be opened following construction completion;
  • Removal of the Second Line West Bridge over Highway 401 to accommodate the highway widening and replacement with a new pedestrian-only structure at the same location;
  • New structures carrying the proposed collector lanes over Fletcher’s Creek;
  • Stormwater management strategy;
  • High mast illumination on Highway 401 throughout the project limits; and
  • Reconstruction of the existing highway pavement.

 

Six (6) lanes will be maintained for traffic for the duration of the project. AECOM has been retained by MTO as the Contract Administrator for this project. The construction contractor is Dufferin Construction Company.

 

Construction is anticipated to commence in April of 2016, and completion is scheduled for the end of September 2019. Throughout the project various traffic stages will be implemented and periodic off-peak lane closures on Highway 401 and interchange ramps will be required to complete parts of the construction operations. There will be one overnight full closure of Highway 401 between Mississauga Road and Mavis Road to facilitate the removal of the Second Line West Bridge, anticipated to occur in the fall of 2016. Construction roadway signing will be employed to provide motorists with advanced notice of upcoming closures. When necessary, signed detours will be provided.
