CAMBRIDGE, Ontario / RankWire.AI / – On Wednesday afternoon, provincial authorities launched emergency traffic reroutes after a serious Cambridge crash involving three vehicles shut down all eastbound lanes of Hwy 401 at Hwy 8. Rescue teams responded to the scene near Speedsville Road around 2:30 p.m., assisting stranded drivers. The collision caused immediate standstill, leading to significant delays for commuters traveling between Cambridge and Kitchener, as traffic management diverted vehicles away from the accident site to grant emergency personnel and cleanup crews access to the wreckage.

The process to remove wreckage and debris was expected to take several hours to reopen the roadway.
