The current
63rd Street Line was the final version of proposals for a northern
midtown tunnel from the
IND Queens Boulevard Line to the
Second and
Sixth Avenue lines, which date back to the
IND Second System of the 1920s and 1930s. In the original 1960s plans, there would have been a station (in addition to or as an alternative to 21st Street–Queensbridge) located farther east at
Northern Boulevard, one block north of the
Queens Plaza station of the Queens Boulevard line. There would have been a pedestrian transfer passageway between the two stations. By October 1980, officials considered stopping construction on the 63rd Street line. Usage estimates for the 21st Street–Queensbridge station were calculated in 1984 at 220 passengers per hour unless a connection was made to the rest of the system. The MTA voted in 1984 to connect the tunnel to the local tracks of the IND Queens Boulevard Line at a cost of $222 million. The section of the line up to Long Island City was projected to open by the end of 1985, but flooding in the tunnel caused the opening to be delayed indefinitely. The MTA's contractors concluded in February 1987 that the tunnel was structurally sound, and the federal government's contractors affirmed this finding in June 1987. This station opened on October 29, 1989, along with the entire IND 63rd Street Line, serving as the line's northern
terminal prior to the connection with the
IND Queens Boulevard Line. The train served the station on rush hours and weekday middays, the train stopped there on evenings and weekends, and the
F terminated here during late nights; all services used the Sixth Avenue Line. The tunnel had gained notoriety as the "tunnel to nowhere" both during its planning and after its opening, with 21st Street being the line's only stop in
Queens. The connection to the Queens Boulevard Line began construction in 1994 and was completed and opened in 2001, almost thirty years after construction of the
63rd Street Tunnel began. Since then, the F train has been rerouted to serve this station at all times. The MTA completed a refurbishment of the station in May 2023. The project included repairing the platforms and stairways, adding lighting, fixing the canopy above the main entrance, and renovating employee rooms. From August 28, 2023, through April 1, 2024, F trains were rerouted via the
53rd Street Tunnel between Queens and Manhattan due to track replacement and other repairs in the 63rd Street Tunnel, and an F shuttle train ran between
Lexington Avenue-63rd Street and 21st Street–Queensbridge at all times except late nights, stopping at
Roosevelt Island. In 2024,
Skanska was hired to replace 21 escalators across the New York City Subway system for $146 million, including six escalators at the 21st Street–Queensbridge station. In April 2025, the 21st Street–Queensbridge station became one of the first New York City Subway stations to have all their
MetroCard vending machines removed, amid the replacement of the MetroCard with the
OMNY fare payment system. On December 8, 2025, the
M train began serving the station on weekdays during the day, running via the 63rd Street Tunnel. The F train began running via the 53rd Street Tunnel during the day, operating via the 63rd Street Tunnel during weekends and nights. == Station layout ==
