Since the station is on a grade, there is a noticeable slant. The station has two side platforms, and there are no overpasses, underpasses, or mezzanines to connect the platforms within fare control. The station was overhauled in the late 1970s. The original trim lines were replaced with white cinderblock tiles, except for small recesses in the walls, which contain blue-painted cinderblock tiles. The staircases were repaired and new platform edges were installed. The blue cinderblock field contains the station-name signs and white text pointing to the exits. The renovation also replaced incandescent lighting with fluorescent lighting. The uptown platform maintains one old style sign while at the north end of the downtown/Brooklyn platform is an entire closed off portion of the platform. There are several old style Rector Street mosaic signs on this platform. Directly to the south, the BMT Broadway Line curves southeast under the Cunard Building and Bowling Green Offices Building to reach the Whitehall Street station.
Exits
Each platform has its own platform-level fare controls. The full-time exit is at the north end of the station, at Rector Street and Trinity Place. The uptown platform contains a token booth and three street stairs: two to the northeast corner of the aforementioned intersection, and one to the southeast corner. The downtown platform is unstaffed and has four street stairs: two to the southwest corner and two to the northwest corner. Just south of the fare control for the downtown platform, there are two exit-only turnstiles leading to an exit-only stair to the western side of Trinity Place. At the extreme south end of the station, there is another street stair from the uptown platform to the northwest corner of Greenwich and Morris Streets, directly across from Elizabeth H. Berger Plaza and the entrance to the separate Rector Street station on the IRT Broadway–Seventh Avenue Line. The downtown platform will become ADA-accessible with the construction of an elevator leading from Trinity Place to the downtown platform. The elevator's installation was required per zoning regulations, which mandated that the developers of 77 Greenwich Street fund transit improvements at the station.
