and Fourth Avenue Lines, was criticized for being dehumanizing. The NYCTA spokesman stated that the old tiles were in poor condition and that the change was made to improve the appearance of stations and provide uniformity. Furthermore, it did not consider the old mosaics to have "any great artistic merit". 2017 Under the Metropolitan Transportation Authority's 2015–2019 Capital Program, the station, along with thirty other New York City Subway stations, were scheduled to undergo a complete overhaul as part of the Enhanced Station Initiative. Upgrades were to include cellular service, Wi-Fi, USB charging stations, interactive service advisories and maps. From January to May 2016, Grimshaw Architects worked on a design for the station's renovation, with Arup Group acting as a consultant. The contract for Package 1 of the renovations, which covers renovations at the Prospect Avenue, 53rd Street, and Bay Ridge Avenue stations on the BMT Fourth Avenue Line, was awarded on November 30, 2016 to Citnalta-Forte Joint Venture for $72 million, the first design–build contract in the subway system's history. The station closed on June 5, 2017 for these renovations, and reopened on November 2, 2017, a month ahead of schedule.

The station has a full curtain wall separating the local and express tracks. The platforms have no columns except on the north ends, where the platforms were extended in 1970. These I-beam columns are cream colored. The ceiling in this area is lower. Prior to the station's 1970 renovation, it was finished all in white and marble tile, and it had its own color scheme to allow regular passengers to identify the station based only on the color of the marble trimmings. Since that renovation, the station walls have consisted of white cinderblock tiles, except for small recesses in the walls, which contain blue-painted cinderblock tiles. The blue cinderblock field contains the station-name signs and white text pointing to the exits. During the 2017 renovation, the cinder block tiles installed in the 1970s were restored, and new black floor tiles and yellow platform treads were installed. The blue cinder block recessions installed
