“manhattan river crossings”

(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 ferry terminal is located near “Battery Park” at Manhattan’s southern tip)

(it is also possible to travel on land to “Staten Island” by way of “Brooklyn”, via the “Verrazano-Narrows Bridge”)

(the “George Washington Bridge”, the world’s busiest motor vehicle bridge, connects “Washington Heights”, in “Upper Manhattan”, to “Bergen County”, in “New Jersey”)

(there are numerous bridges to the “Bronx” across the “Harlem River”, and five of those (listed north to south)—the “Triborough” (known officially as the “Robert F. Kennedy Bridge”), “Ed Koch Queensboro” (also known as the “59th Street Bridge”), “Williamsburg”, “Manhattan”, and “Brooklyn Bridges”—connect “Manhattan” to “Long Island”)

(several tunnels also link “Manhattan Island” to New York City’s outer boroughs and “New Jersey”)

(the “Lincoln Tunnel”, which carries 120,000 vehicles a day under the “Hudson River” between “New Jersey” and “Midtown Manhattan”, is the busiest vehicular tunnel in the world)

(the tunnel was built instead of a bridge to allow unfettered passage of large passenger and cargo ships that sail through “New York Harbor” and up the “Hudson River” to Manhattan’s piers)

(the “Holland Tunnel”, connecting “Lower Manhattan” to “Jersey City”, “New Jersey”, was the world’s first mechanically ventilated vehicular tunnel)

(the “Queens-Midtown Tunnel”, built to relieve congestion on the bridges connecting “Manhattan” with “Queens” and “Brooklyn”, was the largest non-federal project in its time when it was completed in 1940; President “Franklin D. Roosevelt” was the first person to drive through it)

(the “Brooklyn–Battery Tunnel” runs underneath “Battery Park” and connects the “Financial District” at the southern tip of “Manhattan” to “Red Hook” in “Brooklyn”)
