Wikipedia: Houston Street (HOW-stin) is a major east-west thoroughfare in downtown Manhattan. It runs crosstown across the full width of the borough of Manhattan, from Pier 40 on the Hudson River, through the Port Authority Truck Terminal on Greenwich Street, to the East River, and serves as the boundary between the neighborhoods of Greenwich Village and SoHo on the West Side, and between the East Village and the Lower East Side on the East Side. The numeric street-naming grid in Manhattan, created as part of the Commissioners' Plan of 1811, begins immediately north of Houston Street with 1st Street at Avenue A, although the grid does not take full hold until 13th Street.
