Manhattan Being primarily an island, Manhattan is linked to New York City's outer boroughs by numerous bridges, of various sizes. Manhattan has fixed highway connections with New Jersey to its west by way of the George Washington Bridge, the Holland Tunnel, and the Lincoln Tunnel, and to three of the four other New York City boroughs—the Bronx to the northeast, and Brooklyn and Queens (both on Long Island) to the east and south. Its only direct connection with the fifth New York City borough, Staten Island, is the Staten Island Ferry across New York Harbor, which is free of charge. The
History of New York City (1855–1897) movement of the 1950s. Pre-war steam ferries had already made Brooklyn Heights into a bedroom community for affluent professionals on Wall Street and other urban areas. Elevated railroads, operated by the Manhattan Railway Company, and other new public transport expanded the commuter area of New York, allowing development of suburbs for commuters of more modest means in Upper West Side and other distant areas. Plans were made for subways to still more remote exurbs such as Harlem and the West Bronx. In the late 19th century, the island's schist bedrock encouraged the early skyscrapers whose successors characterize its skyline today.
