The westbound express lanes of Highway 401 at Highway 404 in Toronto have reopened following a multi-vehicle crash.
The overnight crash shut down the westbound express lanes along a 10-kilometre stretch of the busy route between Highway 404 and Allen Road.
Ontario Provincial Police said the collision involved five vehicles including three transport trucks.
Authorities said early Thursday morning that three people suffered non-life threatening injuries.
The westbound and eastbound lanes were closed for several hours for the clean-up efforts but reopened just after 8 a.m.
