5 things to know about I-25 and Arapahoe Road

Why is it being done at all?

The project will improve East Arapahoe Road's through traffic by adding a lane in each direction and removing the Interstate 25 bridge supports that used to separate the lanes, officials from the Colorado Department of Transportation said.

Removing those piers has enabled triple-left turns from the southbound I-25 off-ramp to eastbound Arapahoe Road. The project has also widened South Yosemite Street just north and south of Arapahoe Road and realigned the frontage road on the northeast section of the interchange to improve business access, CDOT said.

It's also built walls adjacent to the Walnut Hills area of Centennial to reduce the impacts of traffic noise.

What has been completed? What's still in the works?

The I-25 bridges over Arapahoe Road, paving on I-25, the center median of Arapahoe Road and utility relocation work are all completed, CDOT said.

Improved business access in the northeast part of the highway interchange is in place, and the sound walls have been built near Walnut Hills. Yosemite Street and Arapahoe Road are in their final alignments, CDOT said.

Final paving and striping on Arapahoe Road was scheduled for last weekend. Final paving on Yosemite Street, South Boston Street, South Clinton Street and the I-25 ramps; landscaping, irrigation and aesthetic work; signal and sign installations are yet to be completed. Because some of the work depends on weather conditions, some of it might not be done until spring 2018, CDOT said.

Major closures over

Last weekend's closure of Arapahoe Road between South Dayton and Yosemite streets for final paving should be the last major closure. This fall, there will continue to be short-term lane closures. Major traffic impacts will be over by the end of the year, CDOT said.

Project will cost about $66 million

Construction costs total $66 million, CDOT said. About $50 million is being paid for by CDOT's Responsible Acceleration of Maintenance and Partnerships (RAMP) program. Arapahoe County, the City of Centennial, the City of Greenwood Village and the Southeast Public Improvement Metropolitan District are also providing funding.

Is I-25 getting this treatment in other places?

In Colorado Springs, a project to improve traffic flow by reconstructing the interchange at I-25 and U.S. Highway 24 (West Cimarron Street) is wrapping up in the next few weeks, CDOT said.
