SALT LAKE CITY (AP) — A rare freezing rain caused major havoc in Salt Lake City Thursday, creating sheets of ice on roads, sidewalks and airport runways.

The Salt Lake City International Airport was closed for about three hours, delaying hundreds of passengers. The closure came after a Frontier Airlines plane landing from Denver slid on a patch of ice while on the runway. Nobody was injured.

Morning commutes were brought to a crawl by the icy conditions, which caused dozens of accidents that closed lanes. Utah Highway Patrol called in off-duty officers to deal with all the accidents.
