CDOT to begin roadway and traffic signal improvements on I-25 & Plum Creek/Meadows Parkway

Oct. 17, 2019

DOUGLAS COUNTY — Beginning Oct. 20, the Colorado Department of Transportation (CDOT) and contract partner Interface Communications will begin roadway and traffic signal improvements at four different locations on Interstate 25 including Plum Creek Parkway and Meadows Parkway.  The project has an anticipated completion date of late Nov. 2019.

As part of CDOT’s Whole System Whole Safety initiative, this project will improve safety by removing the deteriorating signal at Meadows Parkway, widening intersections to reduce congestion, upgrading signs to help motorist navigate the new alignment, and adding new traffic detection to improve realtime traffic monitoring. 

Enhancements for the $1.25M project include:

Reducing congestion by adding dual right turn lanes at Meadows Parkway, extending the left turn bay at Castleton Dr. to lengthen and increase the room for traffic, converting the left turn lane at Plum Creek to a triple left turn to better accommodate traffic, installing bridge signs, removing and installing traffic poles, installing new vehicle detectors, widening the roadway, and upgrading the infrastructure.


The project will take place at the following locations:

  • I-25 southbound off ramp; Exit 181 to Plum Creek Parkway
  • I-25 northbound off ramp; Exit 181 to Plum Creek Parkway
  • I-25 southbound off ramp; Exit 184 to Meadows Parkway
  • Meadows Parkway



Motorists can expect the following traffic impacts:

      • East and westbound single lane closures on Meadows Pkwy.
      • Single lane and shoulder closures at I-25 off ramps (Exit 181 and 184).
      • Larger trucks and commercial motor vehicles (CMV) needing to exit on southbound I-25 off ramp at Exit 184, Meadows Creek Pkwy, will need to detour to Castle Rock Pkwy at Exit 185 up to Santa Fe Dr. Detour signs will be in place to direct motorists.

Work will take place Monday through Saturday from 8 am to 4 pm.  Occasional night-time closures will also be required throughout the project.



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.
      • Don't change lanes unnecessarily.
      • 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.
      • Expect delays, especially during peak travel times.
      • Allow ample space between you and the car in front of you.
      • Anticipate lane shifts and merge when directed to do so.
      • Be patient!


Travelers are urged to “know before you go.” Gather information about weather forecasts and anticipated travel impacts and current road conditions prior to hitting the road. CDOT resources include:


To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This initiative takes a systematic, statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.


CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated inter-regional express service. Governor Jared Polis has charged CDOT to further build on the state’s inter-modal mobility options.
