The station opened on October 27, 1904, as one of the original 28 stations of the New York City Subway. As part of the Dual Contracts between the IRT and the Brooklyn–Manhattan Transit Corporation (BMT), the Broadway–Seventh Avenue Line platforms opened in 1917, followed by the Broadway Line platforms in 1918 and the Flushing Line platforms in 1928. The original platforms were also reconfigured to serve the shuttle. The Eighth Avenue Line platforms opened in 1932 as part of the Independent Subway System (IND). The complex has been reconstructed numerous times over the years. The free transfer between the IRT and BMT opened in 1948 while the transfer to the IND opened in 1988. The complex, excluding the IND station, was placed on the National Register of Historic Places in 2004. In the early 21st century, the shuttle station was reconfigured.
Excluding closed platforms, the Flushing Line and shuttle stations have one island platform and two tracks, while the Broadway Line, Broadway–Seventh Avenue Line, and Eighth Avenue Line stations have two island platforms and four tracks.
