Broadway station (IND Crosstown Line)

New York City Subway station in Brooklyn

This underground station has two tracks and two side platforms. The station is between Metropolitan Avenue to the north and Flushing Avenue to the south. The platforms have a light green trim line with a black border and mosaic name tablets reading "BROADWAY" in white sans serif lettering on a black background and light green border. The tiles were part of a color coded tile system used throughout the IND. The tile colors were designed to facilitate navigation for travelers going away from Lower Manhattan. Because the Crosstown Line does not merge into a line that enters Manhattan at either end, all stations on the line had green tiles. The I beam columns in the entire station are dark grey blue, with alternating ones on the platforms having the standard black station name plate in white lettering. Small station signs underneath the trim line read "BROADWAY" in white lettering on a black background. One of the icon tiles on the northbound platform was incorrectly spelled as "BRODAWAY"; this mistake may have been part of the station's original tilework. however, by late February 2020, the tiles with the two wrong letters were permanently swapped.

The station has a small mezzanine above the platforms and tracks at the south end, allowing a free transfer between directions. Two staircases from each platform go up to the mezzanine. A turnstile bank provides entrance/exit from the station. Outside fare control, there is a token booth and four street stairs: one to the southwestern corner of Broadway and Heyward Street, and the remaining three to the southwestern, southeastern, and northeastern corners of Broadway and Union Avenue. The station previously had a full length mezzanine. However, the northern half was closed to the public, and parts of it currently hold offices while the rest of the mezzanine is used for storage space. Despite the lack of a free transfer, temporary free transfers have been offered during construction or service disruptions. A free transfer using a MetroCard between Broadway and Lorimer Street stations was provided during the 14th Street Tunnel shutdown from April 2019 until May 31, 2020, during weekends and late nights. A temporary free MetroCard transfer to and from the Hewes Street station was also made available. These two transfers were honored through the end of May 2020, even though L train tunnel work was completed on April 26.

The north end of the Broadway station has been blocked by false walls. This northern third of the platform level area consists of passages that would have served as transfers to an unfinished station on a level directly above the Crosstown Line tracks (provisionally called South Fourth Street or Union Avenue). The unfinished station was built as part of a planned expansion of the Independent Subway System. The station is a semi complete shell with four island platforms and six track beds, having the same layout as Hoyt–Schermerhorn Streets station. No rails, tiles, lights, or stairs were built. The unfinished station, which is only about as long as Union Avenue is wide, was designed to be the main transfer point from both a line running under Worth Street and a line running under Houston Street coming from Manhattan with the Crosstown Line. These lines would have become two major trunk lines going east; one would have run under Utica Avenue, and the other would have run towards the Rockaways along the Myrtle Avenue and Central Avenue Line. The closed mezzanine area of the Broadway station has stairs at its north end to an upper level mezzanine directly above the unfinished station. This mezzanine has stairs leading to the northern corners of the intersection of South 4th Street, Meserole Street, and Union Avenue.
