In a media release Wednesday evening, the Ministry of Transportation said powerful arctic outflow winds were sweeping the Coquihalla Canyon, and blowing away sand laid down for traction.
Much of southern B.C. remained under extreme cold and arctic outflow warnings on Wednesday.
Traffic cameras in the area showed icy and snowy conditions on the road.
“Icy road conditions with freezing temperatures are creating road hazards that are difficult to maintain and/or manage at this time,” highway contractor Emil Anderson Maintenance posted to Twitter.
DriveBC also said crews responded to a “vehicle incident” somewhere south of the Shylock Road exit.
B.C. Emergency Health Services said it was called about a crash on the highway just before 2:45 p.m. Wednesday.
It deployed six units, including an air ambulance. Three patients were taken to hospital in unknown condition.
