Project Information:
This $66 million Responsible Acceleration of Maintenance Project (RAMP) includes building an additional lane along westbound Arapahoe Road from Yosemite Street to Greenwood Plaza Boulevard, providing three left turn lanes from the I-25 off-ramps, realigning the frontage road in the northeast quadrant of the interchange, building noise walls near the Arapahoe Road and Yosemite Street intersection and widening Yosemite Street from Yosemite Circle on the north to Xanthia Street on the south. This project is designed to reduce congestion and improve traffic operations and safety. Substantial completion is slated for summer 2018.
