RCMP in Leduc have been diverting traffic as they investigate a serious collision.

Cst. Drew Burchette said a pickup truck and a Jetta collided on Highway 814 near Glen Park Road Sunday.

 “When we arrived it appeared that one person inside the Jetta had sustained serious injuries,” he explained.

STARS Air Ambulance was called out to transport the woman, believed to be in her 20s, to hospital.

Three other people were also taken to hospital with less serious injuries, Cst. Burchette told CTV News.

“We’re still waiting for an update on conditions.”

He said the investigation was ongoing and that road conditions were believed to be a factor.
