[AlertDC] DC Water has nearly completed construction site preparation for the Piney Branch Tunnel project, including tree removal, and installation of fences, erosion and sediment controls, utilities, and trailers. To complete site setup a section of Piney Branch Parkway will be relocated before starting the shaft and tunnel work.
On or about May 12, 2026, Piney Branch Parkway will be closed between Arkansas Avenue NW and Beach Drive. The closure is anticipated to last twenty-seven days, weather permitting. Detour signs will be in place to notify and direct motorists to alternate routes. The roadway will be returned to the original alignment at the end of the project |
