The westbound lanes of Highway 401 reopened in the city’s east end on Tuesday after being closed through the morning following a fiery crash.

The highway’s westbound collectors lanes were blocked as emergency responders cleared the scene of a three-vehicle collision, east of McCowan Road in Scarborough.

Ontario Provincial Police say one driver suffered minor injuries in the crash, which caused a tractor-trailer to burst into flames at around 7 a.m.

Fire crews quickly knocked down the blaze, but the closure remained in effect through much of the morning, snarling rush-hour traffic.
