Crews have cleared the wreckage of a tractor-trailer that dangled from an overpass on Highway 401 for nearly seven hours on Saturday.
Earlier, the accident caused lane closures on the busy highway, snarling traffic in the Ajax-Pickering area.
The accident occurred when an 18-wheeler tractor-trailer travelling eastbound collided with two other vehicles around 12:30 pm, said police. The truck driver lost control of the vehicle and hit the guardrail.
After hitting the guardrail, the tractor-trailer caught fire and dangled over an overpass that runs above Church Street.
The driver escaped from the truck and was taken to hospital with minor injuries.
