Dry Creek/I-25 intersection improvement project has begun


The Colorado Department of Transportation, in collaboration with Arapahoe County and the City of Centennial, has started initial work on a project that will make improvements to the intersection of Dry Creek Road and I-25 and expand the number of lanes to the southbound I-25 on-ramp. Motorists should expect delays during the project.

The intersection improvement will take place on westbound Dry Creek Road and includes median widening that will allow more motorists to turn left onto the southbound I-25 on-ramp. The widening of the median will also reduce the likelihood of motorists traveling in the wrong direction on Dry Creek Road. All existing traffic signals at the intersection will be replaced, and pedestrian ramps will be upgraded to American Disabilities Act standards. 

Work on the southbound I-25 on-ramp will feature new metering and three lanes of traffic during peak periods. Additional signage and new striping will also be added.

Work hours for the contractor, KECI Colorado, will range from 7:00 a.m. to 4:30 p.m., Monday through Friday. Motorists will experience single-lane closures, alternating between eastbound and westbound Dry Creek Road, with at least one lane of traffic always open. There will also be shoulder work and single lane closures on the southbound I-25 on-ramp. 

The project is being funded by CDOT, Arapahoe County, City of Centennial, Inverness, Panorama and Southgate at Centennial metropolitan districts. 

Work is expected to wrap up by the end of December. Concerns or questions about the project can be submitted by calling 970-880-4741 or email
