Planned Improvements
Summary of Improved Partial Cloverleaf Interchange Improvements
The planned improvements to the I-25 and Arapahoe Road (State Highway 88) interchange complex will reduce congestion and improve traffic operations and safety.
Final design has been completed, and construction began in May 2016.
The existing partial cloverleaf interchange will be improved through implementation of the following project elements:
- Reconstruct the I-25 bridge over Arapahoe Road and provide three through lanes on Arapahoe Road under the I-25 bridge with a single barrier separating east/west traffic
- Realign the frontage road in the northeast quadrant of the interchange
- Construct an additional westbound lane on Arapahoe Road from Yosemite Street to Greenwood Plaza Boulevard
- Widen Yosemite Street from Yosemite Circle on the north to Xanthia Street on the south
- Construct two noise walls: one along Yosemite Street south of Arapahoe Road to Xanthia Street, and another along the south side of Arapahoe Road from Uinta Street to Yosemite Street
- Provide triple left turns from the I-25 off ramps
