Summary

In Denver, Colorado, a significant infrastructure project is underway as the Denver Department of Transportation and Infrastructure (DOTI) has initiated the replacement of a 136-year-old water main along Santa Fe Drive. This project commenced on August 10, 2026, and is expected to continue until early 2027. The work will take place between 7th Avenue and 12th Avenue, necessitating street closures during the hours of 9 a.m. to 9 p.m. from Monday to Friday. The closures are designed to provide a safe working environment for Denver Water crews as they replace the aging water main.

The project is being conducted in one to two block increments, allowing for some access to businesses along Santa Fe Drive through side streets where work is not occurring. Pedestrian access to these businesses will be maintained throughout the construction period. Local businesses, including Swift's Breakfast House and the Nail and Skin Studio, have expressed their concerns about the impact of the road closures on their operations but remain optimistic due to their loyal customer base. They plan to use signage to inform customers that they are still open for business despite the construction.
