Hand-Tunneling In D.C.

摘要

Extending a new sewer line in Washington, D.C. has posed some serious challenges to local contractor Anchor Construction, particularly when district officials recently opted to locate the new baseball stadium for the Washington Nationals major league team in an area where new development has been welcomed. The location is on the west side of South Capital, just north of the Anacastia River bridge. The site is adjacent to the Navy Yards and the 0 Street Pumping Station. Most of the development created by its new location is occurring to the north, past M Street. This development is further supported by the Metro Station whose entrance is at M Street and New Jersey (the underground station extends a full block to the west and is directly under the new sewer alignment). The development created by the stadium has resulted in new office buildings and 3,000 new condominium units in nine new buildings. In order to accommodate this development, the sewer infrastructure in the area had to be improved, upsized and extended. M Street had to be crossed with a 21-inch diameter line.
