Planes are sitting too long on the ground after getting de-iced so they have to go back and get de-iced again. That caused the airport to put a hold on arrivals.

"The FAA has imposed a ground hold on flights arriving into DIA, so right now nothing is arriving so we can clean the backlog of departures," DIA spokesperson Chuck Cannon said.

About 5,000 people spent the night at the airport. Cannon says officials passed out cots, blankets and mats to make travelers more comfortable.

Cannon says airlines will be extremely busy Wednesday trying to rebook travelers on new flights. The airport is open and operational with three open runways at all times and a fourth being cleared for use.

Heavy snow and winter driving conditions also created problems on Pena Boulevard Tuesday night. Cannon says the road is open Wednesday and mostly clear with occasional slushy spots. Drivers should use caution going to and coming from the airport.
