There is a major highway closure tying up traffic in Milton.
The westbound lanes of Hwy 401 are closed at Guelph Line after a crash involving five vehicles.
Police say one of the transport trucks involved spilled a load of diesel, so the cleanup is expected to take several hours.
Only minor injuries have been reported.
Huge clean up on #Hwy401 WB. Hwy401 WB closed at Guelph line.
