Crews Reduce Closure of I-25 Near Monument Hill to One Night

MONUMENT—Overnight lane closures planned for I-25 near Monument this week have been consolidated into one night instead of the previously scheduled two.

To prepare for construction on the 7-mile southern end of the project—between Greenland Road and Monument—the I-25 South Gap project team will temporarily close a section of northbound and southbound I-25. The closures are necessary for the safety of crews and the traveling public as workers repair and restripe pavement near Monument Hill.

Travel Impacts

• From 8 p.m. Thursday, Nov. 29 through 5 a.m. Friday, Nov. 30, drivers can expect lane closures in both directions of I-25 between CO 105 and Monument Hill.
• Traffic will funnel into one lane around the closures and detour through the weigh station about a half mile north of CO 105.
• Please watch for crews and follow the posted speed limit.

As with all construction schedules, this work is weather-dependent.

Project Info

CDOT is improving 18 miles of I-25 from south of Castle Rock to Monument by widening the road from two to three lanes in each direction. The new lane will operate as an Express Lane, allowing motorists the choice of taking the Express Lane for a faster and more reliable travel time in exchange for a toll, or driving the general-purpose lanes for free. Carpools with three or more people will be able to ride the Express Lane for free.

Other improvements include widening the shoulders, rebuilding bridges, building new wildlife crossings, resurfacing with new pavement and modernizing technology.

This $350 million project is projected to be complete in late 2021, with Express Lanes opening in 2022.
