Fourth Avenue/Ninth Street station
New York City Subway station complex in Brooklyn
The Fourth Avenue/Ninth Street station is a New York City Subway station complex shared by the elevated IND Culver Line and the underground BMT Fourth Avenue Line. It is located at the intersection of Ninth Street and Fourth Avenue in Park Slope, Brooklyn and served by the:
F, G and R trains at all times
D and N trains late nights
W train during rush hours only, with some trips in the peak direction
The Ninth Street portion of the station was constructed as part of the Fourth Avenue Line, which was approved in 1905. Construction on the segment of the line that includes Union Street started on December 20, 1909, and was completed in September 1912. The station opened on June 22, 1915, as part of the initial portion of the BMT Fourth Avenue Line to 59th Street. The station's platforms were lengthened in 1926–1927, and again in 1970. The Fourth Avenue portion was built as part of the Culver Line of the city-operated Independent Subway System, and was constructed as an elevated station so the line could pass over the Gowanus Canal to the west. This station opened on October 7, 1933. The two stations were consolidated into a single station complex on May 28, 1959.

Why this record matters
The subject matters to the places & architecture register because the source frames it as new York City Subway station complex in Brooklyn. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q2135426. Authority coordinates are 40.670, -73.990. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1905, 1909, 1912 and 1915.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
