A 34-year-old man has been charged with careless driving after a tractor trailer flipped on its side in the westbound lanes of Highway 401 in Chatham-Kent.

Chatham-Kent OPP had previously said the westbound lanes of the 401 would be closed at 10 a.m., but they now say the road will be closed for four hours at Kent Bridge Road, beginning at 7 p.m.

OPP say a westbound tractor trailer lost control around 4:30 a.m. and flipped on its side skidding about 500 metres across the westbound lanes of the 401 near Communication Road.

The transport came to rest in the centre media and no injuries were reported.
