The Lexington Avenue Elevated (also called the Lexington Avenue Line) was the first standard elevated railway in Brooklyn, New York, operated in its later days by the Brooklyn Rapid Transit Company, the Brooklyn-Manhattan Transit Corporation, and then the City of New York.
The original line, as it existed at the end of 1885, traveled from Fulton Ferry in Downtown Brooklyn east to East New York, passing over York Street, turning right onto Hudson Avenue (the relevant section is now called Navy Street), left onto Park Avenue, right onto Grand Avenue (which has now been fragmented), left onto Lexington Avenue, right onto Broadway, and slight left onto Fulton Street. The structure above Broadway and Fulton Street is now part of the BMT Jamaica Line. East of Alabama Avenue in East New York, the original structure still exists (albeit reinforced), and is the oldest such structure in the subway system.
The Brooklyn Elevated Railroad opened the line to passengers at 16:00 on May 13, 1885, with a five-cent fare for trains every five minutes. The original line ran from York and Washington Streets (near the Brooklyn Bridge) along York Street, Hudson Avenue, Park Avenue, Grand Avenue, Lexington Avenue, and Broadway to Gates Avenue. The three stations on Park Avenue had island platforms, while all the other stations had two side platforms.
