Project Info

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.

Substantial completion is planned for December 2017.
