The Sierre Tunnel ((フランス語:Tunnel de Sierre)) is a tunnel near Sierre in the Swiss canton of Valais. It is part of the A9 Autobahn and is located between Sierre and Sierre-Est-Ouest. The tunnel was opened in 1999 and consists of two tubes of 2,460 metres (8,070 ft) in length. In a tunnel test by the European Tunnel Assessment Programme (EuroTAP) in 2005 it was rated as "good" – the second-highest grade out of five. The two tubes consist of four linked tunnels, namely, * Alusuisse — 1,070 metres (3,510 ft), * Contoured — 620 metres (2,030 ft), * Crête Plane — 180 metres (590 ft), and * Ancien Sierre Plant Composition — 580 metres (1,900 ft). The Sierre Tunnel came to international attention in March 2012 after a coach crash inside resulted in the deaths of 28 people, including 22 children, who were returning to Belgium from a school skiing holiday. ==References== 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「Sierre Tunnel」の詳細全文を読む スポンサード リンク
