Construction and opening On August 25, 1922, the Transit Commission directed its chief engineer,
Robert Ridgeway, to plan an extension of the Fourth Avenue Line from 87th Street to Fort Hamilton. Initially, multiple stations along the extension were considered. This extension was to be the first part of an extension to
Staten Island through a
tunnel under
The Narrows. On September 12, 1922, a meeting was held by the Transit Commission to determine whether a stop at 91st Street should be included as part of the planned extension. Ultimately, no station was built at 91st Street. At the meeting it was decided that money for an additional station in between 86th Street and the new terminal at 95th Street would be better spent on an extensive terminal with entrances at 93rd, 94th, and 95th Streets. Other extensions were also planned in 1922: a branch of the line running via 86th Street to 18th Avenue to connect with the New Utrecht Line to Coney Island, Route 19, and the future subway under Tenth Avenue, as well as a branch of the line at 67th Street heading to Staten Island, Route 20. On December 28, 1922, the Transit Commission announced that it had awarded the contract for the construction of a half-mile extension of the Fourth Avenue Line, Contract 11B, to T. A. Gillespie Company for $1.5 million (equivalent to $ million in ). However, as the Board of Estimate failed to take action upon it, the contractor withdrew its bid on March 7, 1923. The Transit Commission blamed the Board of Estimate for delays in the awarding of the contract; the Commission said that the city would suffer a substantial loss due to increased construction costs, and because the contract that was given was "highly advantageous to the city." As part of Contract 11B, the extension was built with two tracks, with the exception of a short three-track stretch just north of the terminal at 95th Street. The extension was to be built with a provision to extend the line to Staten Island. As a result of a motion made by Commissioner LeRoy Harkness in front of the Transit Commission, the contract was set to be put back up for bid. On November 2, 1923, the Board of Estimate approved the contract for the line with T. A. Gillespie Company, the same contractor that had bid on the project earlier, but withdrew. The Transit Commission, due to the delay of the project, gave orders on November 3 to speed up the completion of the project. Construction began on December 17, 1923. The final extension to 95th Street, Route 18, opened on October 31, 1925,
Platform extension and elevator installation The city government took over the BMT's operations on June 1, 1940. In the 1960s, the New York City Transit Authority (NYCTA) started a project to lengthen station platforms on its lines in Southern Brooklyn from On July 14, 1967, the NYCTA awarded a contract to conduct test borings at eleven stations on the Fourth Avenue Line, including 95th Street, to W. M. Walsh Corporation for $6,585 () in preparation of the construction of platform extensions. The NYCTA issued an invitation for bids on the project to extend the platforms at stations along the Fourth Avenue Line between
45th Street and this station on May 3, 1968. However, work had already started on the platform extension project in February. The platform at 95th Street was extended by to the south. As part of a plan to increase
accessibility in the New York City Subway, during the early 1990s, the MTA proposed installing elevators at the Bay Ridge–95th Street station by 2010. The agency instead decided to make the 86th Street station accessible, as that station had transfers to more bus routes. In 2017, the MTA indicated that it was considering installing elevators at the
77th Street and 95th Street stations. In December 2022, the MTA announced that it would award a $146 million contract for the installation of eight elevators across four stations, including Bay Ridge–95th Street. The MTA began installing ADA upgrades to the station in 2023, including ramps to station entrances, two elevators, rebuilt staircases, and tactile platform edges. The project was completed in early July 2025. ==Station layout==
