BMT station The
Dual Contracts were formalized in March 1913, specifying new lines or expansions to be built by the
Interborough Rapid Transit Company (IRT) and the
Brooklyn Rapid Transit Company (BRT; later the
Brooklyn–Manhattan Transit Corporation, or BMT). The Dual Contracts included the construction of the
Montague Street Tunnel, which connected the
Broadway Line in
Manhattan with the
Fourth Avenue Line in
Brooklyn at
DeKalb Avenue station. Originally, the only station on the Montague Street Tunnel in Brooklyn was to have been at
Court Street. After the contract was approved for the Montague Street Tunnel and the associated subway line, the planners realized there should have been a station at Lawrence Street. Supporters of the plan said the distance from the south end of the
Court Street station to the north end of the DeKalb Avenue station was apart, much longer than comparable stations on the IRT and BRT in Lower Manhattan and Downtown Brooklyn. On May 16, 1918, the
New York Public Service Commission approved a report by the Chief Engineer requesting that work on the construction of the station stop due to a wartime shortage of materials and men due to
World War I. Only one-ninth of the labor estimated to be required to allow the construction of the station to be completed along with the rest of the line was available. With this reduced labor force, work on this station could not be completed before July 1919, and work on the Court Street station could not be finished before April 1919, following the completion of the Montague Street Tunnel. It was decided to postpone work to complete this station, and use the labor force working on this station and concrete material intended to be used at the station to complete work on the Court Street station, accelerating the estimated completion of that station to January 1919, allowing service through the tunnel to operate in early 1919 as opposed to late 1919. Construction stopped on May 18, when about half the station was completed. Service running through the Montague Tunnel and this station began on August 1, 1920, with the station being constructed alongside in-service trains. Construction resumed on May 18, 1922. The scope of work included excavation from the street to provide an entrance, the construction of an island platform between the two cast iron-lined tunnels covered by a steel and concrete roof, and the construction of a passageway, mezzanine and entrances. On June 11, 1924, the Lawrence Street station opened On March 29, 1993, Lawrence Street was renamed Lawrence Street–MetroTech to celebrate the revival of Downtown Brooklyn with the opening of the MetroTech complex. In response to increased ridership at the station from traffic MetroTech generated, new directional signs were installed, a wall that blocked the view of the token booth clerk was removed to improve security, a part-time token booth was added, and lighting was upgraded.
IND station New York City mayor
John Francis Hylan's original plans for the
Independent Subway System (IND), proposed in 1922, included building over of new lines and taking over nearly of existing lines, which would compete with the IRT and BMT. On December 9, 1924, the
New York City Board of Transportation (BOT) gave preliminary approval for the construction of the
IND Eighth Avenue Line. This line consisted of a corridor connecting
Inwood, Manhattan, to
Downtown Brooklyn, running largely under
Eighth Avenue but also paralleling
Greenwich Avenue and
Sixth Avenue in Lower Manhattan. An additional line, the IND Sixth Avenue Line, was approved in 1925, running from
Midtown Manhattan underneath Sixth Avenue,
Houston Street,
Essex Street, and the
Rutgers Street Tunnel to Downtown Brooklyn. By July 1927, the BOT had finalized its plans for new IND lines in Brooklyn. The Eighth Avenue Line was to continue into eastern Brooklyn as the
Fulton Street Line, while the Sixth Avenue Line was to continue to
South Brooklyn as the
Smith Street (later Culver) Line. The lines were to intersect under Jay Street in Downtown Brooklyn. The Jay Street–Borough Hall station was part of a three-stop extension of the IND Eighth Avenue Line from
Chambers Street in
Lower Manhattan. Construction of the extension began in June 1928. The outer tracks first saw service on March 20, 1933, when the IND Culver Line opened. The IND Sixth Avenue Line to
West Fourth Street–Washington Square opened on April 9, 1936, and the Fulton Street Line to
Rockaway Avenue opened the same day. Until 1969, a free transfer was available to/from the
BMT Myrtle Avenue Line at
Bridge–Jay Streets and also issued at stations from
Sumner Avenue on south. When the Myrtle Avenue Line south of
Myrtle Avenue closed, the transfer was issued to the B54 bus, which ran along the former route. Today, the
MetroCard provides free transfer between bus and subway throughout the system.
Experimental installations and programs In 1955, the city decided to experiment with placing raised safety disks on the edges of the platforms, in order to increase passenger safety. Compared to the painted orange-and-yellow stripes on the platforms, the disks, which were painted yellow and spaced one foot apart from each other, were expected to last about five times as long. The northbound platform's disks were in diameter, and the southbound platform's were . In 1957, the city conducted another experiment, this time placing an automatic token dispenser in the station. In September 1987, the station was the site of yet another experiment; the station's turnstiles were converted to allow new fare payment, consisting of "laminated polyester fare cards." (This would later become the MetroCard, which was not widely released until 1993.) The station's token booths were shuttered in May 2005, after fare tokens were replaced with
MetroCards; station agents were deployed elsewhere in the station to answer passengers' queries. This was part of a pilot program that was tested at seven other stations. In October 2019, the MTA unveiled an accessible station lab at Jay Street–MetroTech station, which was to run until the end of the year. The lab includes over a dozen features including Braille signs, tactile pads, wayfinding apps, diagrams of accessible routes, and floor stickers to guide passengers to the correct routes.
Complex In 1981, the
MTA had listed the IND portion of the station among the 69 most deteriorated stations in the subway system. However, in 2005, planned renovation of twelve subway stations, including the Jay Street and Lawrence Street stations, was delayed indefinitely. The stations were separate from each other since the IND station's opening, despite their proximity. In March 2007, a contract was finally awarded for the renovation of the stations. The $164.5 million project also brought the stations into compliance with the
Americans with Disabilities Act of 1990 and cosmetically improved the upper mezzanine. The transfer was projected to benefit an estimated 35,000 daily passengers. The MTA was hopeful that this instance would encourage developers to build other entrances to other subway stations, since AVA DoBro's developer paid for the entrance in its entirety. New York City councilmember
Lincoln Restler founded a volunteer group, the Friends of MTA Station Group, in early 2023 to advocate for improvements to the Jay Street–MetroTech station and four other subway stations in Brooklyn. The MTA announced in 2025 that a customer service center would open at the station. == Station layout ==
