St. Nicholas Avenue (Manhattan) in the context of "IND Eighth Avenue Line"

The IND Eighth Avenue Line is a rapid transit line in the B Division of the New York City Subway. Opened in 1932, it was the first line of the Independent Subway System (IND); as such, New Yorkers originally applied the Eighth Avenue Subway name to the entire IND system.

The line runs from 207th Street in Inwood south to an interlocking south of High Street in Brooklyn Heights, including large sections under St. Nicholas Avenue, Central Park West, and Eighth Avenue. The entire length is underground, though the 207th Street Yard, which branches off near the north end, is on the surface. Flying junctions are provided with the IND Concourse Line, IND Sixth Avenue Line, and IND Queens Boulevard Line.
