OPP still have the Highway 401 westbound ramp from Highway 24 at Hespeler Road because of an earlier tractor trailer rollover.

Traffic in both directions on the 401 has been backed up for several hours as EMS crews reportedly used the Jaws of Life to extract the driver from the cab.

The tractor trailer rolled over on the on-ramp and the cab separated from the trailer.

Regional Police have been in the area helping to direct the heavy traffic.

Tow trucks are on scene removing debris from the single vehicle accident
