Upper Manhattan

Upper Manhattan is the most northern region of the New York City borough of Manhattan. Its southern boundary has been variously defined, but some of the most common usages are 96th Street, 110th Street (the northern boundary of Central Park), 125th Street, or 155th Street.^{[citation needed]} The term Uptown can refer to Upper Manhattan, but is often used more generally for neighborhoods above 59th Street; in the broader definition, Uptown encompasses Upper Manhattan.^[1]

Upper Manhattan is generally taken to include the neighborhoods of Manhattan Inwood, Washington Heights (including Fort George, Sherman Creek and Hudson Heights), Harlem (including Sugar Hill, Hamilton Heights and Manhattanville), East Harlem, Morningside Heights, and Manhattan Valley (in the Upper West Side).

The George Washington Bridge connects Washington Heights in Upper Manhattan across the Hudson River to Fort Lee, New Jersey, and is the world's busiest motor vehicle bridge.^[2][3]

In the late 19th century, the IRT Ninth Avenue Line and other elevated railroads brought people to the previously rustic Upper Manhattan. Until the late 20th century it was less influenced by the gentrification that had taken place in other parts of New York over the previous 30 years.
