MTA Bridges and Tunnels, legally known as the Triborough Bridge and Tunnel Authority, is an affiliate agency of the Metropolitan Transportation Authority, that operates seven intrastate toll bridges and two tunnels in New York City. In terms of traffic volume, it is the largest bridge and tunnel toll agency in the United States serving more than a million people each day and generating more than $1.5 Billion Dollars in toll revenue annually as of 2012.〔http://web.mta.info/mta/investor/pdf/2013/StantecEngineerReport042613.pdf APPENDIX E History & Projections Of Traffic, Toll Revenues & Expenses April 26, 2013〕 The seven bridges are: * Triborough Bridge (officially Robert F. Kennedy Bridge), its namesake and flagship crossing, connecting Manhattan, the Bronx, Queens, and Randalls and Wards Islands (Manhattan) * Bronx–Whitestone Bridge, connecting the Bronx and Queens * Verrazano–Narrows Bridge, connecting Brooklyn and Staten Island * Throgs Neck Bridge, connecting the Bronx and Queens * Henry Hudson Bridge, connecting Manhattan and the Bronx * Marine Parkway–Gil Hodges Memorial Bridge, connecting Brooklyn and the Rockaways (Queens) * Cross Bay Veterans Memorial Bridge, connecting Broad Channel to the Rockaways (Queens) The two tunnels are: * Brooklyn-Battery Tunnel (officially Hugh L. Carey Tunnel), connecting Brooklyn and Manhattan * Queens–Midtown Tunnel, connecting Queens and Manhattan ==History== Originally named the Triborough Bridge Authority, the authority was created in 1933 as a public-benefit corporation by the New York State Legislature. It was tasked with completing construction of the Triborough Bridge, which had been started by New York City in 1929 but had stalled due to the Great Depression. Under the chairmanship of Robert Moses, the agency grew in a series of mergers with four other agencies: * Henry Hudson Parkway Authority, in 1940 * Marine Parkway Authority, in 1940 * New York City Parkway Authority, in 1940 * New York City Tunnel Authority, in 1946 With the last merger in 1946, the authority was renamed the Triborough Bridge and Tunnel Authority. Generating millions of dollars in toll revenue annually, the TBTA easily became a powerful city agency as it was capable of funding large capital projects. From the 1940s-60s, the TBTA built the Battery Parking Garage, Jacob Riis Beach Parking Field, Coliseum Office Building and Exposition Center and East Side Airlines Terminal,〔(Armode Schwabe, NY Times, 1954 July 12 ) Seven-Month-Old Air Terminal Doing a Good Job for Just About Everone〕 as well as many parks in the city. The TBTA was merged into the Metropolitan Transportation Authority in 1968. Surplus revenue, formerly used for new automobile projects, would now be used to support public transportation. Since then, more than $10 billion has been contributed by the TBTA to subsidize mass transit fares and capital improvements for the New York City Transit, Long Island Rail Road, and Metro-North Railroad. Since 1994, the TBTA has been doing business as MTA Bridges and Tunnels. The name Triborough Bridge and Tunnel Authority is still the legal name of the Authority and was used publicly between 1946 and 1994. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MTA Bridges and Tunnels」の詳細全文を読む スポンサード リンク
