A serious collision involving a tanker truck and multiple vehicles temporarily shut down both directions of Highway 401 near Avenue Road late Friday night.
In a post to social media, the Ontario Provincial Police (OPP) said all lanes were initially closed between Allen Road and Avenue Road as emergency crews responded to the scene.
However by early Saturday morning, officials said eastbound lanes had fully reopened, while westbound lanes remained closed.
One person was taken to hospital with “non-life-threatening injuries,” police noted.
Drivers were previously asked to avoid the area and expect delays.
