The Auckland Harbour Bridge is an eight-lane box truss motorway bridge over the Waitemata Harbour, joining St Marys Bay in Auckland with Northcote in the former North Shore City, New Zealand. It is part of State Highway 1 and the Auckland Northern Motorway. The bridge is operated by the NZ Transport Agency (NZTA).〔(【引用サイトリンク】title= Auckland Harbour Bridge )〕 It is the second-longest road bridge in New Zealand, and the longest in the North Island.〔(What is the longest bridge in New Zealand? ) (from the Transit New Zealand FAQ webpage. Retrieved 9 June 2008.)〕 It is 1,020 m (3,348 ft) long, with a main span of 243.8 m, rising 43.27 m above high water,〔(1951–1961 The Auckland Harbour Bridge Authority ) (Auckland Harbour Board publication, 1960s)〕 allowing ships access to the deepwater wharf at the Chelsea Sugar Refinery, one of the few such wharves west of the bridge, the proposed Te Atatu port not having been built.〔''(Judges favour owner’s descendants in latest – last? – Te Atatu port land case )'' – ''Bob Dey Property Report'', 22 October 2008〕 While often considered an Auckland icon, criticism has included the nickname of 'coathanger' due to its shape, and complaints that it mimics the Sydney Harbour Bridge in copyist fashion.〔("'Get foreign help to build next bridge'" ) – ''Sunday Star Times'', 18 October 2009〕 Many see the construction of the bridge without walking, cycling, and rail facilities as a big oversight. The bridge sees a small number of suicide attempts, with between one and two people each year dying from jumping into the Waitemata Harbour. Bungy operator AJ Hackett operates a 40-m bungy jump from the bridge and offers a bridge climb with views of the city and the harbour.〔(Auckland Bride Climb and Bungy )〕 In 2010, almost 40% of commuters crossing during the 7-9 a.m. morning peak were using buses, a testament to the success of the Northern Busway leading to the bridge (though no bus lanes are on the bridge). ==Background== Prior to construction, the quickest way from Auckland to the North Shore was via passenger or vehicular ferry. By road, the shortest route was via the Northwestern Motorway (then complete only between Great North Road and Lincoln Road), Massey, Riverhead, and Albany, a distance of approximately .〔(Auckland to North Shore: pre-Harbour Bridge )〕〔("The history of the Auckland Harbour Bridge" ) – ''The New Zealand Herald'', 25 May 2009〕 As early as 1860, engineer Fred Bell, commissioned by North Shore farmers wanting to herd animals to market in Auckland, had proposed a harbour crossing in the general vicinity of the bridge. It would have used floating pontoons, but the plan failed due to the £16,000 cost estimate (NZ$1.6 million in 2009 dollars).〔 In the 1950s, when the bridge was built, North Shore was a mostly rural area of barely 50,000 people, with few jobs and a growth rate half that of Auckland south of the Waitemata. Opening up the area via a new road was to unlock the potential for further expansion of Auckland.〔 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「Auckland Harbour Bridge」の詳細全文を読む スポンサード リンク
