Hugh L. Carey Tunnel (Brooklyn–Battery Tunnel)

           The Brooklyn–Battery Tunnel, officially known as the Hugh L. Carey Tunnel, is a toll road in New York City which crosses under the East River at its mouth, connecting the Borough of Brooklyn on Long Island with the Borough of Manhattan. The tunnel nearly passes underneath Governors Island, but does not provide vehicular access to the island. It consists of twin tubes, carrying four traffic lanes, and at 9,117 feet (2,779 m) is the longest continuous underwater vehicular tunnel in North America. It was opened to traffic in 1950. It currently carries the unsigned Interstate 478 (I-478) designation, and formerly carried New York State Route 27A (NY 27A). The tunnel was officially named after former New York Governor Hugh Carey in December 2010.

     Construction began on October 28, 1940 by the New York City Tunnel Authority, with a groundbreaking ceremony attended by President Franklin D. Roosevelt. A large part of Little Syria, a mostly Christian Syrian/Lebanese neighborhood centered around Washington Street, was razed to create the entrance ramps for the tunnel. The shops and residents of Little Syria later moved to Atlantic Avenue in Brooklyn.The tunnel was designed by Ole Singstad and partially completed when World War II brought a halt to construction. After the War, the Triborough Bridge Authority was merged with the Tunnel Authority, allowing the new Triborough Bridge and Tunnel Authority (TBTA) to take over the project. TBTA Chairman Robert Moses directed the tunnel be finished with a different method for finishing the tunnel walls. This resulted in leaking and, according to Robert Caro, the TBTA fixed the leaks by using a design almost identical to Singstad's original.The tunnel opened to traffic on May 25, 1950.

Lincoln Tunnel

       The Lincoln Tunnel is a 1.5-mile-long (2.4 km) tunnel under the Hudson River, connecting Weehawken, New Jersey and Midtown Manhattan, New York City, in the USA. An integral conduit within the New York Metropolitan Area, it was designed by Ole Singstad and named after U.S. President Abraham Lincoln. It is one of two automobile tunnels built under the river, the other being the Holland Tunnel. The Lincoln Tunnel carries a daily average of approximately 108,000 motor vehicles. The tunnel was originally to be named the Midtown Vehicular Tunnel, but the planners eventually decided that the new tunnel deserved a name that was of similar importance to that of the George Washington Bridge, and named it after Abraham Lincoln.

     Designed by Ole Singstad, the tunnel was funded by the New Deal's Public Works Administration. Construction began on the first tube in March 1934.It opened to traffic on December 22, 1937, charging $0.50 per passenger car, equal to $8.73 today.  The cost of construction was $85,000,000, equal to $1,483,271,144 today. 

       Starting on December 1, 2013, the cash tolls going from New Jersey to New York are $13 for both of cars and motorcycles; there is no toll for passenger vehicles going from New York

to New Jersey. E-ZPass users are charged $9.00 for cars and $8.00 for motorcycles during off-peak hours (outside of 6–10 a.m. and 4–8 p.m. on the weekdays; and outside of 11 a.m.–9 p.m. on the weekends) and $11.00 for cars and $10.00 for motorcycles during peak hours (6–10 a.m. and 4–8 p.m. on the weekdays; and 11 a.m.–9 p.m. on the weekends)..

Holland Tunnel

     The Clifford Milburn Holland Tunnel (more commonly known as the Holland Tunnel) is a highway tunnel under the Hudson River connecting the island of Manhattan in New York City with Jersey City, New Jersey at Interstate 78 on the mainland of the United States.

     Begun in 1920 and completed in 1927, the tunnel is named after Clifford Milburn Holland (1883–1924), Chief Engineer on the project, who died before it was completed. Tunnel designer Ole Singstad finished Holland's work. The tunnel is one of the earliest examples of a mechanically ventilated design.

    The tunnel consists of a pair of tubes, each providing two lanes in a 20-foot (6 m) roadway width and 12.5 feet (3.8 m) of headroom. The north tube is 8,558 feet (2,608 m) from end to end, while the south tube is slightly shorter at 8,371 feet (2,551 m). Both tubes are situated in the bedrock beneath the river, with the lowest point of the roadway approximately 93 feet (28 m) below mean high water.
