mezzanine to the street. Station layout There are three overpasses of the IRT Eastern Parkway Line platforms at the mezzanine level above the center of that station. The outer two overpasses have two fare control areas, one each on the north and south sides. The middle overpass is apassageway connecting the unpaid areas on the north and south sides, and has no access to the platforms. The central mezzanine has two bronze plaques commemorating the subway's arrival in Brooklyn: a plaque to the PSC on the west and a plaque celebrating the station's opening on the east. The plaques are installed within mosaic tablets with swag and floral designs. A fourth overpass is at the extreme west end of the IRT Eastern Parkway Line platforms. The center of the northbound Eastern Parkway Line platform has a passageway leading to the southern end of the northbound IRT Broadway–Seventh Avenue Line platform. At the northern end of the IRT Broadway–Seventh Avenue Line platform, there is another mezzanine above the upper platform level. This leads to the BMT platform and two public restrooms inside fare control. Two escalators and two staircases from this passageway go down to a landing above the eastern part of the platform. The BMT Fourth Avenue Line platform has another exit at its extreme western end. From a landing above the platform, two elevators and a staircase go up to the western BMT mezzanine. The mezzanine has a part-time turnstile bank and customer assistance booth. Full height turnstiles provide entrance/exit from the mezzanine at all times. Both Broadway–Seventh Avenue Line platforms are fully accessible under the Americans with Disabilities Act of 1990 (ADA). The northbound Eastern Parkway Line platform is ADA-accessible via the passageway connecting with the northbound Broadway–Seventh Avenue Line platform. However, the southbound Eastern Parkway Line platform and the Fourth Avenue Line platform are not accessible. Accessibility for the southbound Eastern Parkway Line platform was proposed in February 2019 as part of the MTA's "Fast Forward" program. Exits The main fare control for the IRT Broadway–Seventh Avenue Line and BMT Fourth Avenue Line platforms is at the west end of the platforms. Outside fare control, there is a token booth, two staircases going up to the southeast corner of Court and Montague Streets, and a staircase and elevator going up to Columbus Park, the entrance plaza of Brooklyn Borough Hall, on the east side of Court Street.
