Ramp-metering installations along I-25 in Colorado Springs

July 31, 2019 - Southeastern Colorado

El Paso County — The week of August 5, the Colorado Department of Transportation will begin work on Ramp Metering Installations on various on-ramps along I-25 through Colorado Springs. Crews will be installing ramp-metering devices at 12 different locations along the I-25 corridor in Colorado Springs to help ease traffic flow. This project was contracted to Main Electric for $2.5 million.

This project is part of CDOT’s “Whole System. Whole Safety.” initiative aimed at enhancing safety for Colorado’s traveling public. The construction of the ramp-metering devices will make the road safer by improving traffic flow and safety by providing more gaps for merging traffic, provide automated monitoring and will be triggered by I-25 average running speed, and will use technology to monitor the queue and control the flow of traffic. This will be the first installation of ramp meters south of Denver. 


Work will be performed Monday through Thursday. During the day (7:00 a.m. to 5:30 p.m.) drivers can expect shoulder closures on the on-ramps with occasional night-time (7:00 p.m to 6:00 a.m.) lane closures expected. Work is expected to be done on 2 ramps simultaneously beginning from the southernmost, east side ramp working to the north, then crossing over to the western side of I-25 and working toward the south. Ramp metering will be operational on each on-ramp as the work is completed. Work is expected to be completed by early summer 2020, barring weather and /or shipment delays.  

The project is located on 12 different on-ramp locations including:

  • South Academy Boulevard to NB I-25

  • West Bijou Street to NB I-25

  • W. Uintah Street to SB I-25

Project Limits of Construction Work 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.

  • 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!


To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project 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 interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
