Construction leaving the station The 59th Street station was constructed as part of the Fourth Avenue Line, the plan for which was initially adopted on June 1, 1905. The Rapid Transit Commission was succeeded on July 1, 1907, by the
New York State Public Service Commission (PSC), which approved the plan for the line in late 1907. As part of negotiations between New York City, the
Brooklyn Rapid Transit Company (BRT), and the
Interborough Rapid Transit Company for the expansion of the city's transit network, the line was leased to a subsidiary of the BRT. The agreement, known as Contract 4 of the
Dual Contracts, was signed on March 19, 1913. The station's opening was marked with a competition between two trains heading from
Chambers Street station in Manhattan to the Coney Island station, one heading via the
West End Line and the other via the Sea Beach Line; the latter got to Coney Island first.
Modifications and later changes On June 27, 1922, the New York State Transit Commission commissioned its engineers to examine platform-lengthening plans for 23 stations on the lines of the
Brooklyn–Manhattan Transit Corporation (BMT), the successor to the BRT, to accommodate eight-car trains. As part of the project, 59th Street's platforms would have been lengthened from to . Though the Transit Commission ordered the BMT to lengthen these platforms in September 1923, no further progress was made 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. It estimated the project would cost $633,000 (). The NYCBOT received bids for the project on February 25, 1926. The contract was awarded to the Corson Construction Company for $345,021 (). The extensions opened on August 1, 1927. 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 to to accommodate 10-car trains. On July 14, 1967, the NYCTA awarded a contract to conduct test borings at eleven stations on the Fourth Avenue Line, including 59th Street, to the 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 station and
Bay Ridge–95th Street, including this station, on May 3, 1968. However, work had already started on the platform extension project in February. The platforms were extended by to the north. In 1983, the MTA added funding for a renovation of the 59th Street station to its 1980–1984 capital plan. Elevator access for this station had been proposed for the late 2010s. However, the installation of elevators was delayed due to a column replacement project above this section of the Fourth Avenue Line. Both the column replacement and the elevator installation required temporary lane closures on Fourth Avenue, a major artery. An elevator contract was supposed to be awarded in November 2016, but was pushed back to July 2018. A $55.2 million contract for the installation of three elevators at the 59th Street station was awarded in late 2018. Substantial completion was expected in July 2020, but the project was delayed and the elevators opened on November 6, 2020. The final component of the project was completed in June 2021. ==Station layout==
