UPDATE: Westbound Hwy 401 Open

OPP have re-opened the westbound lanes of Hwy. 401 in Woodstock, after closing them twice on Wednesday.

Around 1pm a tractor trailer caught fire on the shoulder of the highway. The trailer was later towed from the scene and the lanes re-opened around 4pm.

But not long after that, the cab of the truck caught fire, forcing the closure of the lanes again. They re-opened around 5pm.
