Traffic Impacts

Week of Jan. 20, 2019

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.

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

Electronic Sign Replacement: Delays Expected Overnight Tuesday-Thursday

Crews will relocate the overhead variable message sign along southbound I-25 near Greenland Road overnight Tuesday, Jan. 22, Wednesday, Jan. 23, and Thursday, Jan. 24.

Traffic impacts:

  • One lane will be closed on southbound I-25 between Tomah and Greenland roads, starting at 8 p.m.
  • The other lane will be intermittently slowed to approximately 10 mph near Upper Lake Gulch Road, starting around 10:30 p.m. each night.
  • All lanes will reopen to traffic by 5 a.m. each morning. 

Concrete Barriers and Slower Speeds Near Monument

Concrete barrier will soon protect a work zone between Greenland and County Line Roads.

Traffic impacts while crews place the barrier:

  • Overnight lane closures on I-25 from 8 p.m. to 5 a.m. Sunday through Thursday
  • Narrower lanes and shoulders
  • 65 mph speed limit

It's expected to take several weeks for all barrier to be in place.

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.
