The Second Sydney Airport is an ongoing proposition for another airport to supplement or replace the existing Kingsford Smith Airport in Sydney, Australia. Estimated to cost between $6 and $8 billion, governments, grappling with the issue since the 1940s, are yet to pursue the issue to anything beyond some preliminary investigations and some precautionary land acquisition. The current designated site for the second Sydney airport is the Western Sydney Airport at Badgerys Creek.〔 Since the construction of Kingsford Smith, aviation in Sydney has grown significantly. Between 1985-86 and 2011-12 total passenger movements through Sydney more than tripled from 9.5 million to 36.0 million. Almost half of all scheduled flights in Australia land or take off at Kingsford Smith, and the airport dealt with 45% of international passengers in 1998. The Federal government made preliminary investigations and purchased land near Badgerys Creek in the 1980s and early 1990s. In May 2013, the Gillard Government released a technical study into the feasibility of Wilton as an airport site. By the time of the 2013 election, the Australian Labor Party had expressed support for the concept of a second airport, but did not support any particular site, whereas the then-Opposition Coalition was split on the issue, with some ministerial support for an airport at Badgerys Creek site while the then-Opposition Leader Tony Abbott had not committed to constructing an airport at all. The second airport was also opposed by the state government of New South Wales, which instead favoured increasing capacity at Kingsford Smith and building a high-speed rail connection between Sydney and Canberra Airport, although doubt had been cast on the viability of the latter option by a study in 2012. After a further study, on 15 April 2014 the Federal government confirmed that the second Sydney airport will be built at Badgerys Creek, as the Western Sydney Airport.〔 ==History== In 1962 the state parliament debated the need for a second airport. It was decided that it should be built because Kingsford Smith had little room to expand. However the need was not urgent and it was decided to defer the planning and construction for at least 10 years. A new government body, the State Planning Authority (SPA) was created to oversee the future development of the region. The SPA had the primary task of planning the development of the new airport and the development of housing sites in the Western Sydney area to suit the growth of Sydney as the major city in Australia. The SPA created a "no development zone" around the Badgerys Creek area in 1964 that would last for 20 years. This would give the government time to plan the airport and the infrastructure for it. This included roads and rail, and flight paths. Sydney was growing fast without the SPA the area would have been subdivided and redeveloped and the airport would have cost far more to build. There was a strong reaction from farmers who owned land in Badgerys Creek. Some wanted to subdivide and take a profit; some wanted to stay and farm the land. Every change of government saw a change to the airport planning and further delays while the politicians tried to buy the now valuable land at a low price and dislodge those who could remember back to 1962 and could see a huge profit from holding out. Around Badgerys Creek 20-litre paint tin lids with crude messages for the SPA were nailed to trees and power poles. These messages stayed until they rusted away and fell off, some lasting 20 years. It is interesting to note that planning for a second airport in Melbourne and Sydney started at the same time, but Melbourne opened its airport in 1970. At the time of the original planning, the Badgerys Creek flight paths were over farm land to the south and over the sparsely populated suburb of Doonside to the north. Aircraft noise would not have been a problem and land would have been marked as Aircraft noise affected, had the plans been revealed. 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「Second Sydney Airport」の詳細全文を読む スポンサード リンク
