The Interstate 25 and Arapahoe Road Interchange Reconstruction project has been completed seven months ahead of schedule, according to the Colorado Department of Transportation.

Construction began in May 2016 with the goal of completing the project by July 2018, CDOT says.

“This project is helping to reduce congestion and improve traffic operations and safety,” said CDOT Executive Director Mike Lewis. “It’s also a great example of partnering. We can accomplish a lot when we pool our collective resources for improving our transportation system.”

Kraemer North America is the general contractor on the $66 million project.

The project involved the following:

  • Reconstructed the I-25 bridge over Arapahoe Road and provided three through lanes on Arapahoe Road under the bridge with a single barrier separating east/west traffic.
  • Realigned the frontage road in the northeast quadrant of the interchange.
  • Constructed an additional westbound lane on Arapahoe Road from Yosemite Street to Greenwood Plaza Boulevard.
  • Widened Yosemite Street from Yosemite Circle on the north to Xanthia Street on the south.
  • Constructed 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.
  • Provided triple left turns from the I-25 off ramps.

CDOT says the project still requires some landscaping and other punch list items through next spring.
