Two people were sent to hospital, one with life-threatening injuries, after their vehicle was struck by a stray tire that flew off a vehicle travelling in the opposite direction on Highway 174 early Thursday morning.

Ottawa police say the tire flew off a westbound vehicle in the area of the Blair Road exit just after midnight.

It struck a vehicle going the other direction.

Two people were taken to hospital, including one with life-threatening injuries.

The highway was closed until around 5:30 a.m.
