The Colorado Dept. of Transportation began in mid-July a $97.5-million project along the North I-25 corridor from 120th Avenue to Northwest Parkway/E-470 to expand the Express Lanes.

This previous Express Lanes project was completed on I-25 between U.S. 36 and 120th Avenue. The new project will add capacity on I-25 up to Northwest Parkway/E-470 and construct a new asphalt surface from 120th Avenue to S.H. 7. CDOT says the roadway will be in its final alignment by winter 2018.

“I-25 plays a critical role in the quality of life and economic vitality in the growth of northern Colorado, and this stretch is one of the most congested portions of highway in the Denver metro area, seeing an average daily traffic volume of 174,000 vehicles per day,” says Paul Jesaitis, CDOT Region 1 transportation director. “Ultimately, this project will positively impact so many motorists, providing benefits to local businesses, neighborhoods as well as through traffic.”

CDOT, contractor Hamon Infrastructure, the city of Westminster, the city and county of Broomfield, the city of Northglenn, the city of Thornton and Adams County are playing a big role in the project.

The project was funded in part through collaboration with Responsible Acceleration of Maintenance (RAMP), CDOT Region 1 Surface Treatment, Highway Safety Improvement Program, CDOT Water Quality Mitigation Fund and a loan secured by CDOT’s High Performance Transportation Enterprise.
