The Borough Hall/Court Street station is an underground New York City Subway station complex in Brooklyn shared by the BMT Fourth Avenue Line, the IRT Broadway–Seventh Avenue Line and the IRT Eastern Parkway Line. The complex comprises three stations: Borough Hall on the IRT lines and Court Street on the BMT line. The stations are located under Court, Joralemon, and Montague Streets, next to Brooklyn Borough Hall, in the Downtown Brooklyn and Brooklyn Heights neighborhoods of Brooklyn. It is served by the 2, 4, and R trains at all times; the 3 train all times except late nights; the 5 train on weekdays; the N train during late nights; and limited rush-hour W trains.
The Borough Hall station of the Eastern Parkway Line was built for the Interborough Rapid Transit Company as part of the city's first subway line. The station opened on January 9, 1908, when the original IRT was extended into Brooklyn.
