The widening of north I-25 continues as the Colorado Department of Transportation continues roadway reconstruction work. Crews will be installing a new overhead message board over I-25 during the nighttime hours of April 12-14. This operation will require full closures of northbound I-25 between Colorado Highway 392 and Harmony Road.

When complete, the project will also increase capacity on I-25 by adding an Express Lane in both directions, constructing inside and outside shoulders, and replacing aging bridges. The project will also improve multimodal access to regional transit.


Full closures of northbound I-25 between CO 392 and Harmony Road nightly from 9 pm until 5 am, April 12 through April 14.

Northbound I-25 traffic will use Exit 262/ CO 392, turn right and continue east to County Road 17/Colorado Highway 257. Turn left and go north on CO 257 to Harmony Road. Turn left on Harmony Road and continue west to the northbound I-25 on-ramp.
