This station has two tracks and two side platforms.
South of this station, there are two center stub tracks ending at bumper blocks used for laying-up and relaying trains.
Further south, the two tracks of the BMT Nassau Street Line merge with the BMT Broadway Line via a flying junction as it enters the Montague Street Tunnel into Downtown Brooklyn.
No regular service has used this connection since the M train was re-routed from the Nassau Street Line to the IND Sixth Avenue Line in June 2010.

Trains terminate on the southbound track, then continue to one of the two relay tracks before returning on the northbound track to start northbound service to northern Brooklyn and Queens.

This station was renovated in the late 1990s and a mosaic design was added the platform walls.
Beneath a small green and gold trim-line is a larger gold trim-line with a maroon border and white "B" and "BROAD ST" tablets on a blue-green background at regular intervals.
