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. Traffic runs downtown (southbound) along the full stretch from Chelsea to the Upper West Side, except for the lowermost three blocks (from Gansevoort Street to 14th Street) where traffic runs northbound carrying traffic from Greenwich Street. Description 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. The portion of the avenue between 14th and 31st Streets was remodeled in 2008 with a bicycle lane between the eastern curb and the parking lane, followed by another portion between 77th and 96th Streets in 2011. 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
