This platform was connected to the island platform with an underpass at its northern end. Escalators and stairs connect both platforms to the mezzanine below track level, where free transfers can be made between the two platforms. On the uptown platform, pairs of escalators and staircases lead to the mezzanine, while on the downtown platform, alternating staircases and escalators descend to the mezzanine. There are two banks of turnstiles on the north and south sides of the mezzanine, which is outside fare control. A pair of escalators and a staircase leads from the eastern end of the mezzanine to an upper mezzanine, which contains the token booth, and a bank of turnstiles, which leads directly onto the uptown side platform. Two elevators make the station accessible under the Americans with Disabilities Act of 1990. One connects street level, the main northbound fare control, and the southbound fare control area below the platforms and tracks. The other connects the Brooklyn-bound platform with the fare control area below. South of the station, the tracks diverge into two sets. One set (the inner tracks) enter the Joralemon Street Tunnel to travel to Brooklyn. this route is used by the 4 train at all times and the 5 train on weekdays until 8:45 pm. The outer tracks continue to the closed South Ferry inner loop station, which is used by the 5 train when it short turns at this station during weekends and late weekday evenings. The station has three street stairs, an elevator, a set of escalators, and an original control house (also known as a head house). These exits are clustered in three separate locations. The eastern end of the upper mezzanine, toward the center of the station, leads to a pair of staircases and an up escalator that leads to Bowling Green plaza. There is a glass-canopied stairs-and-escalator entrance in front of the Alexander Hamilton U.S. Custom House, just around the corner from two entrances to the Whitehall Street–South Ferry station on the BMT Broadway Line (which are set into the building's eastern elevation). At the eastern end of the lower mezzanine, a pair of escalators and a staircase lead to an intermediate level. This, in turn, leads to a pair of staircases on the north side of Battery Place between Greenwich Street and Broadway, outside the International Mercantile Marine Company Building. A staircase, at the southern end of the island platform, leads to a fare control area in the restored control house. which consists of a pair of low turnstiles at the south end, and two high entry/exit turnstiles flanking the staircase down to the platform.
