59th Street is a crosstown street in the New York City borough of Manhattan, running from York Avenue/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. The street is mostly continuous, except between Ninth Avenue/Columbus Avenue and Columbus Circle, where the Time Warner Center is located. While Central Park South is a bidirectional street, most of 59th Street carries one-way traffic.
