History of the Green Line
The Green Line was the last major WMATA line to enter service, opening in stages between 1991 and 2001. The initial segment connected Anacostia, L'Enfant Plaza, and Gallery Place. Extensions north to Greenbelt and south to Branch Avenue completed the current route by 2001.
The line was instrumental in the revitalization of the U Street corridor — once the heart of African-American cultural life in DC, then devastated by the 1968 riots, and now one of the city's most vibrant entertainment districts. Columbia Heights and Shaw have similarly transformed in the years since the Green Line opened.

Navy Yard & Nationals Park
Navy Yard–Ballpark is the go-to stop for Washington Nationals games. The station is less than a 5-minute walk to the main Nationals Park gates. On game days, Green Line trains run with increased frequency and extended service — check the WMATA game-day schedule for the last train time after night games.
