Full overnight closures of Southbound I-25 near Monument  Sept. 23 and Sept. 24

Travel Advisory

September 22, 2020 - Southeastern Colorado - Motorists are asked to stay the course and expect delays

DOUGLAS/EL PASO COUNTIES – Southbound Interstate 25 approaching Monument is planned to close this Wednesday and Thursday nights for pavement repairs. Motorists traveling southbound in this area can expect up to 20-minute delays during the closure.  They will drive around the closure using the ramps at County Line Road.   

Traffic Impacts

  • From 8 p.m. to 7 a.m. Wednesday, Sept. 23, and Thursday, Sept. 24, drivers should expect to use the southbound I-25 off- and on-ramps at County Line Road to detour around paving work. Traffic will funnel into one lane before detour via the ramps.
  • Access to I-25 from County Line will be open, but delays should be expected.
  • There are no alternate routes, so drivers are asked to allow extra time to stay the course on I-25. Visit cotrip.org for current, estimated travel times.
  • All work is weather-dependent and subject to change.

Please see map at end of release.

 As summer ends, the window for paving operations, which depend on warm and consistent temperatures, closes. Before winter hits, crews are planning to repair pavement along southbound I-25 near County Line Road. This area has been prone to potholes, so the project team will mill the pavement and replace it before winter weather can cause further damage.

CDOT is improving 18 miles of I-25 between Monument and Castle Rock by widening the highway 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, more reliable travel time in exchange for a toll. Express Lanes will be free to vehicles with three or more people and motorcycles. All travelers will have the choice of taking the general-purpose lanes for free.

The project also includes shoulder widening, rebuilding bridges, new wildlife crossings, resurfacing with new pavement and modernizing technology. Project completion is scheduled for 2022.
