The westbound lanes of the 401 were shut down at the Provincial (County Rd 46) off ramp Sunday afternoon to remove a jackknifed tractor trailer.

Around 9:00 a.m. Sunday morning, a 42 year old Brampton man was driving lost control of his rig and drove off the highway.

He was transported to area hospital with serious non-life threatening injuries.

The investigation is continuing and charges have not been laid at this time.
