Highway 401 in Cambridge will be closed overnight Saturday as crews demolish the Hespeler Road southbound bridge.
The closure between Hespeler Road and Townline Road will begin at 9 pm on Saturday April 30. The highway is set to reopen at 10 am on Sunday May 1.
All traffic will be detoured and major delays are expected, the province said in a public notice. Motorists are advised to avoid the area.
The work is part of a multi-year project that will see Highway 401 through Cambridge widened from six lanes to 10 lanes.
