Widening/reconstruction of Approximately 39 km of Highway 401 (Addition of One Lane in the Median in Each Direction) and Construction of a Concrete Median Barrier
Preliminary Design and Initiate Detail Design Group C Class EA

This Group Work Project includes the widening of Highway 401 (addition of one lane in the median in each direction) from the Chatham-Kent/Elgin County Boundary to 2.0 km west of Union Road. In addition, median concrete tall wall barrier and a storm sewer system will be installed throughout the limits. Associated drainage, bridge, and culvert improvements will also be undertaken to facilitate the highway widening, including the widening/rehabilitation of Fleming Creek Bridge, replacement of six structural culverts, and extension of 7 structural culverts.

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.

Existing median emergency turn-arounds will not be available during or after construction, as the concrete median barrier will be installed. 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 signage of construction on Highway 401 will be provided.
