Ninth Avenue originates just south of West 14th Street at
Gansevoort Street in the
West Village, and extends uptown for 48 blocks until its intersection with West
59th Street, where it becomes
Columbus Avenue – named after
Christopher Columbus. It continues without interruption through the
Upper West Side to West
110th Street, where its name changes again, to
Morningside Drive, and runs north through
Morningside Heights to
West 122nd Street. A one-block stretch of Ninth Avenue between 15th and 16th Streets is also signed as "Oreo Way". The first
Oreo cookies were manufactured in 1912 at the former
Nabisco headquarters on that block. Above the
Lincoln Square neighborhood—where the
ABC television network houses its corporate headquarters in a group of rehabilitated and modern buildings—Columbus Avenue passes through the
Central Park West Historic District, stretching from 67th/68th Streets to 89th Street. There, the avenue presents a unified streetscape of 5- to 7-story tenement buildings of brick and
brownstone with discreet
Romanesque and
Italianate details, employing
cast terracotta details and panels and courses of angle-laid brickwork. Many ornate tin
cornices remain. The buildings are separated in mid-block by the narrowest of access alleys, giving glimpses of
Ailanthus foliage in the side-street yards. The repeated designs of three or four commercial speculative builders, using the same features and detailing, add to the avenue's architectural unity. There are several generously scaled pre-
World War I apartment buildings and the former
Endicott Hotel, as well as a small commercial block from the office of
McKim, Mead, and White at
72nd Street. Between 77th and 81st Streets, Columbus Avenue borders the
American Museum of Natural History and Theodore Roosevelt Park. Ninth Avenue reappears in the
Inwood neighborhood as a short two-way street in two segments interrupted by the
New York City Subway's
207th Street Yard. It runs from West 201st Street to West 208th Street, dead-ending at Inwood North Cove Park at the
Harlem River, then picks up again at West 215th Street, and terminates at Broadway between West 220th Street and the
Broadway Bridge, at the location where West 221st Street would normally be. The addresses along this upper stretch from 201st Street to Broadway are continuous with the lower portion of Ninth Avenue. ==History==
