Two people were killed and four more were transported to hospital after the third serious crash on Highway 1 in the B.C. Interior in a week.

The crash closed the highway between Revelstoke and Golden for several hours Saturday.

Mounties in Golden said a man and a woman believed to be from Delta were killed at the scene.

Four others were transported to hospital by air ambulance, two in critical condition and two in serious condition, CTV News reports.

BC Emergency Health Services said it was called to the scene just after 11 a.m. Three ground ambulances and two air ambulances responded.

The highway was closed for four hours as a result of the crash. Golden-Field RCMP said they are investigating the incident, along with the BC Coroners Service.

DriveBC reported that the incident happened 19 kilometres east of Glacier National Park.

Saturday's crash marks the third time in four days that the highway has been closed by a motor vehicle accident. On Wednesday, a dump truck driver was killed after losing control of his vehicle and striking several other vehicles on the road.

The following day, a semi-truck jack-knifed on the same stretch of road, blocking both lanes of traffic for several hours. The driver in that single-vehicle crash was treated for non-life-threatening injuries.
