A 24-year-old woman was flown to hospital in Calgary by STARS Air Ambulance after a crash on a highway north of the town of Cochrane on Saturday.
RCMP say emergency crews responded to the scene, at the intersection of Highway 22 and Highway 567, at approximately 11 on Saturdays.
Officials say STARS was also called to the scene.
Officials with the service say a 24-year-old woman was flown from the scene to Foothills Medical Center in Calgary in critical condition.

“At this point, between the two vehicles, there were seven occupants,” said Cpl. Susan Richter with the RCMP.
“Four had minor to moderate injuries, two were transported to hospital and one is in critical, life-threatening condition.”
