Widening/Reconstruction of Approximately 10 km of Highway 401 (Addition of One Lane on the Outside in Each Direction) and Underpass Improvements
TESR Review and Initiate Detail Design Group B Class EA

This Group Work Project includes the widening of Highway 401 (addition of one lane on the outside in each direction) from 1.0 km west of Highway 4 (Colonel Talbot Road) to Wellington Road. In addition, median concrete tall wall barrier and a storm sewer system will be installed. Associated drainage, bridge, and culvert improvements will also be undertaken to facilitate the highway widening, including the widening of Wonderland Road Overpass, and rehabilitation of Dingman Creek Culvert.

Timing for construction is subject to funding and approvals.

Construction staging and traffic management will be confirmed during the design process. Temporary lane and interchange ramp closures will be required to facilitate construction of the proposed improvements.

Advance notice of closures (lane, ramp, etc.) will be distributed to local municipalities and emergency service providers.

Motorists and commercial haulers traveling through the study area may experience temporary delay or disruption during construction. Advanced signing of construction on Highway 401 will be provided.

The design of the Highway 401/Highway 4 (Colonel Talbot Road) Interchange improvements, including the replacement of the Glanworth Drive Underpass, is being undertaken as a separate project by Dillon Consulting Limited.
