A tractor trailer has tipped while navigating a curved approach at Highway 401 near Highway 400 leaving it teetering over the eastbound lanes of the 401 Monday morning. OPP posted images on Twitter showing a transport truck leaning against the guard rail over Highway 401. The vehicle was carrying heavy paper rolls which it seems likely were not fully secured inside the truck. It happened some time around 8:30 a.m. on the eastbound Highway 401 ramp at Highway 400. OPP Sgt. Kerry Schmidt said collector lanes have reopened, but express lanes will remain closed until crews put the truck upright over the next hour. He said one person suffered minor injuries in the rollover.
