CONSTRUCTION PROGRESS ON THE DC CLEAN RIVERS PROJECT

摘要

On October 12, 2011, with federal, regional, and local officials present-and a headline banner running in lights across the display in Times Square-the US$2.6 billion DC Clean Rivers Project officially broke ground. Construction began on the 7,378 m (24,200 ft) long, 8 m (26.3 ft) diameter Blue Plains Tunnel. Within a year, construction began on a new overflow and diversion structure near RFK Stadium (Division C), a diversion tunnel system on M Street Southeast (Division E), a diversion tunnel beneath Interstate 695 at the 11th Street Bridge Project (Division G), and a diversion tunnel on Tingey Street (Division B). This paper discusses the status of DC Water's construction progress on the DC Clean Rivers Project.
