 The Park Service also proposed extending East Capitol Street onto the reclaimed land and then over the Anacostia River, and building a complex of sports stadiums, an armory, an outdoor theater, a swimming pool, an ice skating rink, and athletic fields on the flats.Legislation proposing a bridge across Kingman Island and stadium complex in Anacostia Park was submitted to Congress, which did not act on the proposals.The first nine holes of Langston Golf Course were built on the north end of Kingman Island in 1939, and the back nine on the lake's western shore in 1955.
