Denver Water is set to begin a project to replace nearly five miles of aging pipe along East Colfax Avenue.

Denver Water and the Regional Transportation District (RTD) are coordinating to minimize impacts to bus routes throughout the project. The project will begin in the intersection of East Colfax Avenue and Broadway, requiring a full closure of the intersection.

Later this month, crews will begin work on East Colfax Avenue between Broadway and Yosemite Street, working in two- to three-block segments at a time. The entire project should be completed by the end of 2024.

The first segment, from Broadway to Sherman Street, will be completed at night, with lane closures in each direction on East Colfax Avenue from 7 p.m. to 7 a.m. Work will then take place during daytime hours for the remainder of the project.

Work will occur Monday through Friday, although some weekend work may be required. Construction schedules are also subject to change due to weather and may be altered to accommodate major events in Denver.

Commuters should expect delays in this area. Local access to residences and businesses will be maintained throughout the project. For more information or to sign up to receive updates, please visit

The pipe replacement work is taking place in advance of the upcoming East Colfax Bus Rapid Transit project, which is being led by the Denver Department of Transportation and Infrastructure, in partnership with RTD, Colorado Department of Transportation, the Federal Transit Authority and the city of Aurora.
