I-25 interchange finished ahead of time

January 1, 2018 by  

Reconstruction of a notoriously congested interchange—Interstate 25 and Arapahoe Road in Centennial—has finished seven months early.

At a ceremony in the morning the day the work finished, hard hats filled the air as officials tossed them to celebrate.

The reconstruction effort began in May 2016, and was slated to finish in the summer of 2017. Funding came from the Colorado Department of Transportation’s Responsible Acceleration of Maintenance and Partnerships Program, with matching funds coming from the Southeast Public Improvement Metropolitan District, Greenwood Village, Arapahoe County, and Centennial itself.

Kraemer North America was the contractor on the project, which included putting in six through lanes on Arapahoe Road, three in each direction, and rebuilding the bridge that carries I-25 over Arapahoe Road. In addition to the work on the main interchange, Kraemer built an additional westbound lane between Greenwood Plaza Boulevard and Yosemite Street on Arapahoe Road; widened Yosemite Street between Xanthia Street and Yosemite Circle; and added two noise abatement walls, among other improvements. A punch list of final tasks will be finished in the spring.

According to traffic counts conducted by the state, over 250,000 vehicle go through the interchange on I-25 every day, with another 70,000 traveling on Arapahoe Road in the same period.

Major developments like this are important to residents of the area, so officials might want to work with a postcard printing company to create a mailer to announce the status of the project.
