TRAFFIC ADVISORY: Temporary Lane Closures Rock Creek and Potomac Parkway for Sewer Rehabilitation Project
DC Water will be performing repairs to the Rock Creek Main Interceptor (RCMI) within the West End and Georgetown Neighborhoods. This will require temporary lane closures beginning tonight, February 27, at 8 PM through Monday, March 2, at 5 AM.
The construction plan initially announced in early October involves two phases. During the first phase, crews will perform work to help restore one of two sewer gates located within a structure along the trail. Once completed, crews will move on to the second phase of the project, now expected to start in early 2026. These repairs are a high priority to prevent potential sewage discharge into Rock Creek and are part of DC Water’s Capital Improvement Program.
DC Water is continuing to conduct additional field investigations and inspections needed to complete the first phase of work.
Temporary Lane and Trail Closures:
One lane of the Rock Creek and Potomac Pkwy NW (South Bound) between P Street and Pennsylvania Ave NW will be closed full-time during the Gate Restoration.
