Brooklyn Bridge station with the BMT Centre Street Loop Subway's (now BMT Nassau Street Line) Chambers Street station. On July 1, 1948, post-unification, many free transfers between the former systems were created coincident with the doubling of the fare from five to ten cents. The most recently created station complex is the Jay Street–MetroTech complex in Brooklyn on the IND Culver Line, IND Fulton Street Line and BMT Fourth Avenue Line; opened on December 8, 2010. The Court Square complex in Queens, which opened in 1988 as a connection between the IND Queens Boulevard and IND Crosstown lines, was expanded by adding a passageway to the IRT Flushing Line on June 3, 2011. A free transfer from Broadway–Lafayette Street to the uptown platform of Bleecker Street opened on September 25, 2012. A transfer to the downtown platform has existed since May 19, 1957. A passageway between Cortlandt Street and World Trade Center opened on December 29, 2017, along with a connection to the World Trade Center Transportation Hub. A passageway between the Times Square and Bryant Park station complexes was built in 2021, along with a new platform at the shuttle station (both the platform and passageway are closed during late nights). Manhattan Lower Manhattan (14th Street and below) Former transfers When the elevated IRT Third Avenue Line closed from Chatham Square to South Ferry on December 22, 1950, a paper transfer was given to the M15 bus route. The Third Avenue Line was closed in Manhattan on May 12, 1955, removing this transfer. When the new "H" system was implemented on August 1, 1918, the Public Service Commission was unprepared for the heavy traffic using the 42nd Street Shuttle. The shuttle was closed for rebuilding at the end of August 3, and a paper transfer was added between Rector Street on the IRT Broadway–Seventh Avenue Line and Wall Street on the IRT Lexington Avenue Line (the only one of the two lines to go to Brooklyn at that time). Shuttle service resumed on September 28, 1918, but the transfer remained, and was expanded to allow transfers from Wall Street on the Brooklyn Branch of the Broadway–Seventh Avenue Line, its temporary end. After the Brooklyn Branch was completed on April 15, 1919, the transfer was no longer needed. There was never a free transfer between the IRT Broadway–Seventh Avenue Line (outer) and IRT Lexington Avenue Line (inner) platforms at South
