The westbound lanes of Highway 403 at the Lincoln Alexander Parkway have been reopened Friday afternoon after a fatal crash Friday morning.
Shortly before 10 a.m., a Toyota Tundra collided with a tractor trailer when the Tundra moved into the right lane to pass traffic, according to police.
The passenger of the Tundra, a 59-year-old Toronto woman, was pronounced dead at the scene, said Sgt. Dave Woodford with the OPP. There were no injuries to either driver of the two vehicles.
The police are not releasing the name of the victim until next of kin is notified, Woodford said.
The collision is being investigated by the OPP. Witnesses are asked to call 905-681-2511.
The collision shut down all westbound lanes of the highway for several hours for investigation. The highway was cleared shortly after 3 p.m., Woodford said.
