Ninth Avenue, known as Columbus Avenue between West 59th and 110th Streets, is a thoroughfare on the West Side of Manhattan in New York City, United States. Traffic runs downtown (southbound) from the Upper West Side to Chelsea. Two short sections of Ninth Avenue also exist in the Inwood neighborhood, carrying two-way traffic.

59th Street is a crosstown street in the New York City borough of Manhattan, running from York Avenue and Sutton Place on the East Side of Manhattan to the West Side Highway on the West Side. The three-block portion between Columbus Circle and Grand Army Plaza is known as Central Park South, since it forms the southern border of Central Park. There is a gap in the street between Ninth Avenue/Columbus Avenue and Columbus Circle, where the Deutsche Bank Center is located. While Central Park South is a bidirectional street, most of 59th Street carries one-way traffic.
