Traffic Impacts

Week of Nov. 18

Until now, the most active construction has been on the northern end of the project, near Castle Rock. Crews are now preparing to start construction on the southern end of the project, between Monument and Greenland Road. Drivers will start to see pre-construction activities there as soon as next week.

In observance of the Thanksgiving holiday, there are no planned lane closures next Thursday, Nov. 22 through Sunday, Nov. 25. Any closures that do take place are related to unplanned, emergency road repairs or response to an incident on the roadway.

Remember: two lanes of traffic on I-25 will be open in each direction during the day. While all planned lane closures on I-25 are restricted to nighttime, emergency repairs or response to motor vehicle crashes may require daytime closures. Sign up for text alerts by texting I25GAP to 21000.

Safety Alert

Narrower lanes and shoulders give crews room to work in the I-25 center median between Plum Creek Parkway and Sky View Lane (Tomah Road), where the new Express Lanes and wider shoulders will be built. But that also means the corridor is tight for motorists.

Please pay close attention through the construction zone. Watch your following distance and avoid distracted driving. 

Watch for Haul Trucks on I-25

Trucks are frequently accessing the work zone in the I-25 center median on the northern end of the project to remove dirt. Delays are expected. Please:

  • Watch for trucks entering and exiting the work area
  • Give truck drivers a break - yield to allow trucks to merge
  • Allow plenty of following distance
  • Follow posted speed limits
  • Do not follow trucks into the work zone

Project Offices in Castle Rock

A temporary construction office for CDOT and its contractor partner, Kraemer North America, is located near the intersection of Crystal Valley Parkway and the I-25 east Frontage Road. Please watch for vehicles entering and exiting the site throughout the duration of construction. Upon project completion, the area will be returned to its previous state; the asphalt will be removed and the area will be re-graded and seeded.


Safety for drivers and workers is our top priority during construction.
