Already congested Interstate 25 and Interstate 70 are about to get even more crowded as people start hitting the road for the holiday weekend.

The Colorado Department of Transportation is expecting an additional 10,000 cars to hit the highways on Wednesday alone.

Bob Wilson with CDOT said the best thing to do in holiday traffic is to give yourself plenty of time.

“Our heaviest traveled day of the holiday weekend traditionally is Wednesday and it goes down significantly on Thursday,” Wilson said.

He said he thinks you should be prepared to see traffic pick back up Friday and last throughout the weekend into Sunday.

“I-70 is supposed to be really busy as well as I-25 and even the local roads around the mall areas,” Wilson said.

To help minimize the cluster of cars, CDOT came up with a plan for its workers.

“We will stop all construction at noon on Wednesday and they won't be on the road until Monday," he said. "The only way you would see someone on the roadways is an emergency like a huge pothole opened up.”

Crews will be on standby for areas that could get bad weather.

“If we get weather they will be out with the snow plows especially in the high country," added Wilson.

It’s not just the roads that are going to be crowded DIA is also anticipating about 70,000 travelers on Wednesday and an increase throughout the holiday weekend.

DIA employees are asking people to be at least two hours early so they can get everyone through security and on their flights.
