Construction on the segment of the line that includes Bay Ridge Avenue started on January 24, 1913, and was completed in 1915.

[9][10] Progress on the extensions did not occur until February 16, 1925, when the New York City Board of Transportation (NYCBOT) commissioned its engineers to examine platform-lengthening plans for this and eleven other stations along the Fourth Avenue Line.

[15][16] In the 1960s, the New York City Transit Authority (NYCTA) started a project to lengthen station platforms on its lines in Southern Brooklyn to 615 feet (187 m) to accommodate 10-car trains.

[17] On July 14, 1967, the NYCTA awarded a contract to conduct test borings at eleven stations on the Fourth Avenue Line, including Bay Ridge Avenue, to the W. M. Walsh Corporation for $6,585 (equivalent to $60,172 in 2023) in preparation of the construction of platform extensions (equivalent to $60,172 in 2023).

The latter change, which was also made to 15 other stations on the BMT Broadway and Fourth Avenue Line, 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.

[22][23] From January to May 2016, Grimshaw Architects worked on a design for the station's renovation, with Arup Group acting as a consultant.

[28] Plans for the Interborough Express, a light rail line using the Bay Ridge Branch right of way, were announced in 2023.

The blue cinderblock field contains the station-name signs and white text pointing to the exits.

[42] The landing in the southbound platform's second entrance had been the only area in the station that contained the original 1915 trim line with "B.R."

The 2017 artwork at this station called Strata consists of a set of tile mosaics by Katy Fischer, which commemorate the Native American, Dutch, and English colonial histories of the area.

The station is designed to allow the northbound platform to become the Manhattan-bound express trackway if the two additional tracks were built.

[51][52] From the mezzanine outside of fare control, two staircases lead to either southern corners of Bay Ridge and Fourth Avenues.

[45][54][55] Two platform level turnstiles lead to a small landing, where a double-flight staircase goes up to the northwest corner of 68th Street and Fourth Avenue.
