Signed as National Highway 1/A1, it forms part of Highway 1 and the Australian National Highway network linking Perth and Adelaide. It was named after explorer Edward John Eyre, who was the first to cross the Nullarbor by land in 1840–1841. The Eyre Highway runs from Norseman in Western Australia, past Eucla, to the state border. Continuing to the South Australian town of Ceduna, it then crosses the top of the Eyre Peninsula before reaching the city of Port Augusta in South Australia. The construction of the East–West Telegraph line in the 1870s, along Eyre's route, resulted in a hazardous trail that could be followed for interstate travel. A national highway was called for, but the federal government did not see the route as important enough until 1941, when a war in the Pacific seemed imminent. The highway was constructed between July 1941 and June 1942, but was trafficable by January 1942. Though originally named Forrest Highway, after John Forrest, by the war cabinet, it was officially named and gazetted Eyre Highway, a name agreed upon by the states' nomenclature committees. The finished road, while an improvement over the previous route, still wasn't much more than a track, and remained such throughout the 1940s and 1950s. Efforts to seal the highway began in Norseman in 1960, with the Western Australian section completed in 1969 and the South Australian section finished in 1976. ==Route description== Eyre Highway is the only sealed road linking the states of Western Australia and South Australia.〔 From Norseman in Western Australia, the highway travels east for across the Nullarbor Plain to Ceduna, South Australia. It then crosses the top of the Eyre Peninsula as it continues eastwards for , before reaching the city of Port Augusta. Eyre Highway is part of the National Highway route between Perth and Adelaide, and also forms part of Australia's Highway 1. It is signed as National Highway 1 in Western Australia, and National Highway A1 in South Australia. The vast majority of the highway is a two-lane single carriageway〔 with a speed limit of , except in and around built up areas.〔 〕 Road trains (A-double or B-triple) up to are permitted on the Eyre Highway,〔(【引用サイトリンク】title=RAVnet online mapping system )〕 but are limited to the slightly lower maximum speed of . The Western Australian section of the Eyre Highway is on the western side of the Nullarbor Plain. The South Australian section of the Eyre Highway crosses the eastern section of the Nullarbor Plain, and the top of the Eyre Peninsula. The Nullarbor gets its name from Latin for 'no trees', and the typical view is that of a straight highway and practically unchanging flat saltbush-covered terrain, although some parts are located on ridges. The Eyre Peninsula has been extensively cleared for agriculture, although there are remnant corridors of native eucalyptus woodland alongside it's roads. 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「Eyre Highway」の詳細全文を読む スポンサード リンク
