The Aktio–Preveza Undersea Tunnel is an undersea road tunnel across the mouth of the Ambracian Gulf in western Greece. It links Epirus and the city of Preveza on the north shore of the gulf with the cape of Aktio (Actium) in Aetolia-Acarnania, in Central Greece. Completed in 2002, the tunnel is an important piece of infrastructure in a previously underdeveloped region, and greatly shortens the travel distance between the two sides of the gulf, which previously was only possible by ferry. It is the first and so far only undersea tunnel in Greece.〔〔(【引用サイトリンク】publisher=akteotunnel.com )〕 ==Technical characteristics== The tunnel has a total length of 1570 metres and consists of:〔 * An underwater section of total length 909 metres.〔 * A cut and cover section of length 509 metres on the north (Preveza) side.〔 * A cut and cover section of length 152 metres on the south (Aktio) side.〔 The tunnel has a cross-section height of 8.6 metres and width 12.6 meters.〔 The clearance width is 10.6 metres and clearance height is 5.4 metres.〔http://www.skyscrapercity.com/showthread.php?t=192115〕 The tunnel is a dual way carriage way and includes a 4.0 metre-wide side lane and a 1.3 metre wide pedestrian sidewalk in each direction.〔 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「Aktio–Preveza Undersea Tunnel」の詳細全文を読む スポンサード リンク
