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. Substantial completion is planned for December 2017.
