Stadium–Armory is an island platformed Washington Metro station in the Kingman Park neighborhood of Southeast Washington, D.C., United States. The station was opened on July 1, 1977, and is operated by the Washington Metropolitan Area Transit Authority (WMATA). Stadium–Armory serves the Blue, Orange and Silver Lines. The station was supposed to be the Silver Line's eastern terminus, but in December 2012, due to safety concerns regarding a pocket track between this station and Minnesota Avenue (the first station to the east on the Orange Line), Metro officials decided to extend the line into nearby Prince George's County, Maryland to Largo Town Center, which is the eastern terminus of the Blue Line. It is a transfer station for the Blue/Silver and Orange lines, as this is the last station shared by the three lines before the lines diverge going east. The station has entrances on 19th Street at C Street and Independence Avenue.
