I-25 Ramp Metering in Southeast Colorado

Project completed

About the Project

The Colorado Department of Transportation in collaboration with SEMA Construction, announces the completion of the I-25 ramp metering installation project in Colorado Springs. The project enhances safety and mobility through Colorado Springs.

The southbound Woodmen Road on-ramp, northbound and southbound Academy Boulevard on-ramps and the northbound North Gate Boulevard on-ramp were widened, and ramp meters were installed. The ramp meters enhance roadway safety and improve I-25 congestion through the spacing and pacing of vehicle entry onto the interstate. Intelligent Transportation Systems (ITS) were installed to monitor, trigger, and time vehicle release with automated vehicle and queue detection to mitigate any traffic backups by adjusting meter timing.
