October 16, 2017 - Denver Metro Colorado/CDOT Region 1 - GREENWOOD VILLAGE – The Colorado Department of Transportation (CDOT) will close various Interstate 25 ramps at the Arapahoe Road interchange this week for final lane striping.


These closures will be as follows:

8 p.m. to 5:30 a.m., Monday, Oct. 16 through Thursday, Oct. 19 - Various on- and off- ramp closures at Arapahoe Road. Use Orchard or Dry Creek roads as alternate routes.

The project team reminds motorists to allow extra time for your commute, adhere to speed reductions on I-25 and Arapahoe Road and avoid distractions. Alternate routes are advised. Watch for weekly construction update emails with the most up-to-date information regarding traffic impacts.

Project Information: This $66 million Responsible Acceleration of Maintenance (RAMP) Project 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.
