A section of Deerfoot Trail was shut down in both directions for almost four hours on Monday night after a loose wheel struck a car, critically injuring one of the occupants.
Police said a half-ton pickup truck was southbound on Deerfoot Trail near McKnight Boulevard Northeast at around 5 p.m., when the left-rear tire and rim detached.
The truck was in the lane closest to the median at the time, and the wheel travelled across the centre barrier and hit a northbound sedan.
“The tire struck the sedan on the passenger side of the roof causing significant damage to the passenger compartment,” police said in a Monday news release.
Neither of the drivers were injured, police said, but a woman in the front passenger seat of the sedan suffered serious, life-threatening injuries.
Alcohol, drugs and excessive speed are not considered factors in the collision, according to police.
Anyone who may have witnessed the crash is asked to call the Calgary Police Service’s non-emergency line at 403-266-1234 or to contact Crime Stoppers anonymously.
