Summer construction on I-70 moves forward

Eastbound commutes and trips to DIA may be impacted by the project


A proposal for construction on Interstate-70 has been delayed until August, but the Colorado Department of Transportation and Kiewit Meridiam Partners plan to move forward with other aspects of the project.

The construction project includes a 10-mile stretch of I-70 from Brighton Boulevard to Chambers Road.

This summer, the companies will launch construction with utility relocation. Both CenturyLink and Xcel Energy will move 10 miles worth of power transmission and long-haul fibers. Kiewit Meridiam will move 20 miles worth of storm sewer pipes and three miles of water lines and sanitary sewers. During this phase, 46th Avenue between Brighton Boulevard and York Street will be permanently closed. As of now, it is the only full-road closure planned during construction.

While neighborhood streets are under construction, CDOT officials are recommending drivers use the highway as much as possible.

Kiewit Meridiam had initially hoped to have a nighttime construction schedule for work on I-70, saying it would speed up the project.

However, residents of the area voiced concerns about pollution and noise.

The company had intended to present a proposal during the July 12 Denver Board of Public Health and Environment meeting, but decided to postpone it until August.

The meeting will be held on Aug. 9 in the community room of the animal shelter at 1241 W. Bayaud Ave.

The biggest portion of the project will take out the 54-year-old viaduct, lowering the interstate from Brighton to Colorado boulevards.

Neighborhood crossroads that originally passed under the viaduct will be replaced above the highway along with a new 4-acre park. CDOT anticipates the construction will continue through 2022.

CDOT will also be adding an express lane in each direction on the interstate.
