It is part of the National Highway system spanning Australia, and is signed as National Highway A8. The Dukes Highway starts in Tailem Bend on the Princes Highway and extends southeast to the state border near Bordertown, South Australia. The highway continues in Victoria as the Western Highway, with the same route signage (National A8). The length of the highway on the South Australian side is around 191 km, joining onto the Western Highway which is 443 km. Generally, the quality of the Dukes Highway is of a high standard, with the entire road having wide lane widths and sealed shoulder. The final 17 km of the highway after Bordertown, was originally built on unstable ground but was re-constructed in 2005.〔(【引用サイトリンク】title=Dukes Highway pavement rehabilitation )〕 The Dukes Highway runs along the northern side of the Limestone Coast region of South Australia. The route and many of the settlements (including Bordertown) were established in the 1850s to supply water to horses for the gold escorts from the Victorian goldfields to Adelaide.〔From interpretive signs in Bordertown and along the route〕 Gold was taken to Adelaide rather than the closer Melbourne because a higher price was offered there. The higher price was offered to stop the South Australian economy from collapsing as all the labourers were heading to the Victorian Goldfields. The 'Bullion Act' was passed and an Assay office was established in Adelaide for the assaying and stamping of gold in 1852. It is claimed that this saved South Australia from bankruptcy.〔The Story of Keith 1851-1973, Fry, LPH 1953〕 ==Major road accidents== The Dukes highway accounts for one third of South Australia's road fatalities, many as head-on collisions, leading to calls for road improvements to separate traffic in each direction. Point-to-point speed cameras have been installed on one section of the highway to identify drivers who flaunt the speed limit. Parts of the highway have had wider centre lines installed with audio tactile treatment to help drivers to realise and recover from drifting across the centre line before they encounter an oncoming vehicle. This is intended to reduce fatigue and inattention-related crashes. Motorists are advised to rest and recover at the many towns on the Dukes Highway, including Bordertown, Keith, Tintinara, Coonalpyn and Tailem Bend, where the Dukes Highway ends. 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「Dukes Highway」の詳細全文を読む スポンサード リンク
