(CNN) -- A United Airlines jet slid off a taxiway in Spokane, Washington, early Tuesday while getting ready to fly to Denver, an FAA spokesman said.
There were 175 people on board and none were injured, Spokane International Airport spokesperson Todd S. Woodard.
Flight 812 was scheduled to depart the Spokane airport around 5:30 a.m. (8:30 a.m. ET) Tuesday when the incident occurred, according to the United website.
Passengers were taken off the plane and bused to a terminal, he said. The airport is temporarily closed while officials there "take measures to assure adequate braking conditions" are in place, said Woodard.
It was not clear if weather played any role in the incident. The National Weather Service reported sub-freezing temperatures and mostly cloudy skies in Spokane on Tuesday morning.
Located near the Idaho border some 250 miles from Seattle, Spokane International Airport is the second-largest airport in Washington state.
According to its website, some 3 million passengers flying on six airlines and 64,000 tons of cargo pass through Spokane International Airport each year.
