Frontier flight from Denver to Salt Lake City slides on runway

SALT LAKE CITY - A Frontier Airlines flight from Denver to Salt Lake City slid on the runway Thursday morning.

Airport spokeswoman Barbara Gann said the airplane slid off the runway.

However, Frontier Airlines says the plane did not slide off the runway, but it did encounter ice while taxing and slid. Frontier Airlines says the plane had to be towed to the gate.

There are no reports of injuries, Gann said.

The Salt Lake City International Airport was closed after the incident due to icy conditions and poor friction on the runways.

One runway reopened about three hours later, at 12:45 p.m. 

Five flights were canceled and 15 other planes were forced to return to their gates after the runway was closed.

Freezing rain in northern Utah also caused dozens of accidents on roadways around Salt Lake City Thursday morning.
