Three people survive boulder crushing car in work-zone section of B.C. highway

KELOWNA, B.C. - A boulder crushed a car on a highway in B.C.'s Okanagan Valley Friday but the three people inside survived.

The RCMP say the boulder, weighing up to 136 kilograms, landed on the hood of a White Dodge sedan travelling south on Highway 97 near the community of Oyama, north of Kelowna.

The front end of the car was crushed, injuring the male driver and a woman passenger.

Police say they were taken to hospital but their injuries are not believed to be life-threatening, while a third person in the car was not hurt.

The RCMP say the incident happened below an area of road construction and an investigation has been launched into how the rock came loose.
