Several express and collector lanes of Highway 401 are closed following a crash involving a tractor-trailer Friday night.
Ontario Provincial Police say three express lanes and three collector lanes of the eastbound highway between Bayview Avenue and Yonge Street are closed after a car and tractor-trailer collided just after 6 p.m.
The crash left the tractor-trailer straddling the median between the collector and express lanes and police say diesel fuel has spilled onto the highway.
No injuries have been reported.
Police say a large portion of the highway is expected to be closed for several hours as crews work to clean up the spill.
