AAA Colorado predicts more than 1.6 million people in the state will drive or fly between Wednesday and Jan. 3, up slightly from 2014.
The fact that Christmas and New Year’s Day are on Friday this year gives travel numbers a boost, says AAA’s Wave Dreher.
"It means that just about everybody is getting a long weekend, or two long weekends," Dreher said. "There are a lot of people planning two trips this year."
Low gasoline prices are also a factor. In Colorado, gas is about 50 cents a gallon less than at this time last year.
Weather might be a factor in the mountains. On Tuesday, avalanche work closed several mountain passes.
