Simcoe St. and Albert St. bridge replacement over Highway 401
A 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 this project, M.T.O. is undergoing work to complete the replacement of the Simcoe St. S. and Albert St. overpass structures in Oshawa. The need to replace these structures with wider structures was identified through the Ministry's Environmental Assessment process to accommodate the future widening of Highway 401 through Oshawa.
Construction of the structure replacement is anticipated to begin in June and be phased over five stages in the 2023/2024 construction seasons. The anticipated completion date of all construction works is November 2024.

All closure setups will be done in accordance with Ontario Traffic Manual - Book 7 - Temporary Conditions.
