In June, Denver Water will begin a project to replace nearly five miles of aging pipe along East Colfax Avenue from Broadway to Yosemite. Denver Water and RTD are coordinating to minimize impacts to bus routes throughout the project. RTD customers are encouraged to check RTD Service Alerts for details about bus detours around the work.

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. Local access to residences and businesses will be maintained throughout the project. For more information or to sign up to receive project updates, please visit

The pipe replacement work is taking place in advance of the upcomingEast 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.
