ADAMS COUNTY—Travelers can expect several daytime closures Thursday, Nov. 1 through Saturday, Nov. 3, as crews finalize the new traffic alignment for right-turning vehicles from eastbound 120th Avenue to southbound I-25.

Because this requires paving, crews are taking advantage of favorable weather during the day to complete this work, which will ultimately reduce congestion in the area.

All work is weather permitting and subject to change. Motorists should plan to add 10 minutes to their travel time to detour around the closures.

Project Info

The North I-25 Express Lanes project from 120th Avenue to Northwest Parkway/E-470 is a $97.5 million project that will improve safety, capacity and user choice to a rapidly developing region.

This project will continue the previous Express Lanes project, which was completed on I-25 between US 36 and 120th Avenue, and will extend the Express Lanes to Northwest Parkway/E-470. The project will add capacity on I-25 up to Northwest Parkway/E-470 and construct a new asphalt surface from 120th Avenue to Colorado Highway 7. Motorists can expect the roadway to be in its final alignment by early 2019.
