RCMP are investigating after a semi, grain auger and SUV collided on Highway 1 Wednesday afternoon.

The crash happened just before  4 p.m. at Highway 1 and Road 42 near Portage la Prairie.

RCMP said a Chevy Traverse was driving westbound on Highway 1 when it collided with a grain auger being towed by a pickup truck. The truck was turning onto Road 42, RCMP said.

Then, a semi rear-ended the Chevy.

The 45-year-old woman driving the Chevy SUV was rushed to hospital with unknown injuries. Her 18-year-old passenger was also taken to hospital but for precautionary measures, RCMP said.

The other two drivers were not injured in the crash.

An RCMP traffic analyst is now investigating.
