The
IND Culver Line is a
rapid transit line of the
B Division of the
New York City Subway, extending from
Downtown Brooklyn south to
Coney Island, Brooklyn, New York City, United States. From its beginning at an
interlocking north of
Jay Street – MetroTech, where Culver Line trains can access the
IND Sixth Avenue Line or
IND Eighth Avenue Line, south to
Church Avenue in
Kensington, the line is mostly a four-track subway, though it rises to cross over the
Gowanus Canal on the only above-ground structure on the original
Independent Subway System. In Kensington, a ramp allows the line to rise onto a three-track elevated structure built by the City for operation by the
Brooklyn Rapid Transit Company as part of the
Dual Contracts. When this ramp was opened in 1954, the older route from Kensington northwest to
Sunset Park remained as the
Culver Shuttle until it was closed in 1975. The final portion of the line in Coney Island is on the lower level of a double-decked elevated structure, with the
BMT Brighton Line above.
