Drivers are Urged to Slow Down and Pay Attention

  • The entire interchange, including the Quadrant Intersection, has been designed to properly function once the project is fully operational. The project team continuously works with the City of Colorado Springs Traffic Department to monitor and adjust signal timing as needed to improve the flow of traffic.

  • Speed reduction to 55 mph on I‐25 between South Nevada Avenue/Tejon Street and Cimarron/US24 (northbound and southbound)

  • Speed reduction to 45 mph on I‐25 from Cimarron/US24 to Bijou Street (northbound and southbound)

  • Slow down, observe speed limits, avoid distractions, and allow extra time for your commute.

  • Please be patient.

PROJECT INFORMATION: The $113 million I-25/Cimarron Interchange Design-Build Project involves rebuilding the I-25 interchange between Colorado Avenue on the north and South Nevada Avenue to the south, 8th Street on the west and the Cimarron Street over Fountain Creek bridge on the east. Improvements are intended to provide enhanced operations, correct existing safety and design deficiencies, and to serve the anticipated short- and long-term travel demands in this area. When complete, this will be a high-functioning interchange that safely handles more vehicles and enhances multi-modal travel for those using I-25, US 24/Cimarron Street and the trail system along Monument and Fountain creeks. Project fully operational before Dec. 1, 2017.
