I-25 South Gap Crews Extend Active Work Zone to the South This Week

Nov. 20, 2018 -

EL PASO COUNTY—Crews this week began working on the southern end of the I-25 South Gap project between Greenland Road and Monument—an addition to the five-mile northern stretch (between Castle Rock and Sky View Lane, aka Tomah Road) where crews have been and will continue working since breaking ground in September.

Work on this seven-mile stretch at the southern end of the project will result in wider shoulders, new Express Lanes, new wildlife crossings, a new interchange at Greenland Road and the flattening of vertical curves approaching the Greenland Road exit. Work zones will vary along this portion of the corridor; some will be in the center median, while others will be on the outside. At some point, all traffic will be shifted to the sides of I-25 to reconstruct the bridge at Greenland Road.

To prepare before building work zones, crews will repair asphalt and restripe pavement.

Travel Impacts

  • From 8 p.m. to 5 p.m., Sundays through Thursdays, expect single-lane closures, with narrowed lanes and shoulders.
  • Speeds will be reduced.
  • Please pay attention to and drive appropriately for the changing roadway conditions.
  • Watch for trucks entering and exiting the center median.
  • Please maintain a safe following distance, obey all posted speed limits, allow trucks to merge and do not follow trucks into the work zone.

Construction will be in full effect across the entire 18-mile corridor by summer 2019. All construction schedules depend on weather.

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 and motorcyclists 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. The cost of the project is $350 million. Substantial completion of the project is expected in late 2021, with Express Lanes opening in 2022.
