Navy Yard–Ballpark is a Washington Metro station in Washington, D.C. on the Green Line. The station is located in the Navy Yard/Near Southeast neighborhood of Southeast, with entrances on M Street at Half Street and New Jersey Avenue.Station layoutNavy Yard–Ballpark uses the island platform layout with two tracks. Track F1 is used by trains to Greenbelt while Branch Avenue-bound trains use track F2.HistoryA station serving the Navy Yard area existed in original plans for Metro; however, the routing of the Green Line below proved controversial. In 1976, the original routing was rejected as too costly and disruptive. A new study proposed a more westerly path which would move the Anacostia station west, replace the Good Hope Road station with one at Congress Heights, and terminate at a station (named "Rosecroft" in plans and Metro maps) near Brinkley Avenue and Rosecroft Drive in Fort Washington instead of Branch Avenue in Suitland. During December 1977 public hearings, this route was criticized as disserving poorer landowners in the area, but Washington Metropolitan Area Transit Authority (WMATA) approved the western route in 1980, scheduled to open in 1986. Supporters of the Branch Avenue route then took the case to the U.S. District Court.
