Extended closures and detours on I-25 between Larkspur and Monument for paving and traffic shifts starting tonight

October 30, 2020 - Central/Eastern Colorado

Check project website for current information before traveling 

DOUGLAS/EL PASO COUNTIES– As part of the Colorado Department of Transportation’s Interstate 25 South Gap project, drivers along I-25 near Larkspur and Monument can expect delays from extended closures or short detours using the off- and on-ramps almost nightly until late-November as crews repair pavement and prepare for traffic shifts. Delays will be up to 30 minutes, mainly in the evenings and mornings. 

Tonight, Oct. 30 from 8 p.m. to 8 a.m., drivers can expect a full closure of I-25 near Larkspur for drainage work. Detours will be via off- and on-ramps. 

Additional extended closures will be necessary over the next several weeks for pavement work. The asphalt pavement needs time to cool before I-25 reopens. Once these closures are complete, motorists will be driving on new pavement, which should minimize potholes and make for a safer drive this winter and during adverse weather. Overall, the project will place 850,000 tons of asphalt to provide a smoother driving surface along the entire 18-mile project work zone. To date, nearly 50% of paving is complete on the project. 

Because asphalt work requires warmer temperatures, this work is heavily impacted by weather. Crews will complete as much paving as possible before winter, so the closure schedule is expected to vary and fluctuate with weather. 

Motorists can expect almost nightly impacts through late-November and should check i25gap.codot.gov or the project’s Facebook page (@I25SouthGapProject) for up-to-date, detailed closure and detour information before traveling I-25 between Monument and Castle Rock. All work is weather dependent and subject to change. Generally, construction impacts are expected to include:

If a closure is cancelled due to weather or other unforeseen circumstances, crews will look for another opportunity to complete this important paving work. During these closures, drivers may see crews setting up cones and signs up to an hour prior to closure start time. There are no alternate routes, so drivers must stay the course on I-25 and plan for delays up to 30 minutes. Check cotrip.org for estimated travel times before driving through this area. 

Check the I-25 South Gap website and Facebook page for current information on all closures. Text I25GAP at 21000 for text updates on all closures.

ABOUT THE PROJECT
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.

REMEMBER: SLOW FOR THE CONE ZONE

The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.
  • Stay Alert! Expect the unexpected.
  • Watch for workers. Drive with caution.
  • Anticipate lane shifts and merge when directed to do so
  • Expect delays, especially during peak travel times.
  • Allow ample space between you and the car in front of you.
  • Avoid using mobile devices such as phones while driving in work zones.
  • Turn on headlights so that workers and other drivers can see you.
  • Be especially alert at night while driving in work zones.
  • Be patient!
