Wilson Rd. S. closure for Highway 401 / Wilson Rd. overpass replacement

The Ministry of Transportation (M.T.O.) project is underway for Highway 401 rehabilitation and long-term widening needs from Brock Rd. to Courtice Rd.

As part of the project, M.T.O. is undergoing work to replace the Wilson Rd. S. overpass structure along Highway 401 in Oshawa. This project includes lowering Wilson Rd. and making improvements to the surrounding embankments, retaining walls, noise barriers, drainage, lighting, and signage.

As part of the construction, there will be a long-term full closure of Wilson Rd. S. from Dieppe Ave. to Bloor St. E. Construction is set to begin on March 24, 2025 and is expected to be completed by late 2026. During this time, both lanes of Wilson Rd. will be closed from Dieppe Ave. to Bloor St.
