Two lanes of southbound Highway 427 are open to traffic after a multi-vehicle collision closed all lanes near Airport Road early Tuesday morning.
A tractor-trailer jackknifed after 4 a.m., and a second truck slammed into it, OPP Sgt. Kerry Schmidt tweeted from the scene. At least two cars were also involved in the collision.
A dusting of snow led to a "flash freeze," Schmidt said, which "created very slippery conditions."
Shortly after 6 a.m., sanders and sweepers were at the scene cleaning up a small fuel spill on the road that followed the collision. The Ministries of the Environment and Transportation have been notified about the incident, Schmidt said.
The crash was just one of several accidents on GTA highways Tuesday after the overnight snowfall.
Westbound Highway 401 near Highway 427 was closed for a time, but has since reopened. And the eastbound lanes of the 401 reopened before 6 a.m. after being closed for a five-vehicle crash near Carlingview Drive. That collision also involved a jackknifed tractor-trailer.
Other minor crashes occurred on Highways 409 and 410, as well.
