The Chambers Street station is an express station on the IRT Broadway–Seventh Avenue Line of the New York City Subway, located at the intersection of Chambers Street and West Broadway in the TriBeCa and the Financial District neighborhoods of Manhattan, it is served by the 1 and 2 trains at all times, and by the 3 train at all times except late nights.

The station was built by the Interborough Rapid Transit Company (IRT) as part of the Dual Contracts with New York City, and opened on July 1, 1918.

[8] It was predicted that the subway extension would lead to the growth of the Lower West Side, and to neighborhoods such as Chelsea and Greenwich Village.

[9][10] Chambers Street opened as part of an extension of the line from 34th Street–Penn Station to South Ferry on July 1, 1918.

[11][13] The new "H" system was implemented on August 1, 1918, joining the two halves of the Broadway–Seventh Avenue Line and sending all West Side trains south from Times Square.

[14] An immediate result of the switch was the need to transfer using the 42nd Street Shuttle in order to retrace the original layout.

[22] The walls of the station contain mosaics depicting Columbia College's old campus nearby, between Murray, Church, and Barclay Streets and West Broadway.
