Truck rollover blocking eastbound lanes of Highway 401

The eastbound lanes of Highway 401, east of Trafalgar Road, are closed after a rollover involving a tractor-trailer.

The Ontario Provincial Police say the truck went through a centre wall on the highway, which has resulted in leaving the left lane of the highway closed at the moment.

The truck driver was not hurt, police say.

It is not immediately clear when the eastbound lanes and the single westbound lane will reopen.
