Hvalfjörður Tunnel (''Hvalfjarðargöng'' in Icelandic) is a road tunnel under the Hvalfjörður fjord in Iceland and a part of Route 1 (Iceland's ring road). It is 5,770 m long and reaches a depth of 165m below sea level. Opened on 11 July 1998, it shortens the distance from Reykjavík to the western and northern parts of the island by 45 km. Passing the fjord now takes 7 minutes instead of about an hour before. Spolur was the company that constructed, and is now the owner and operator of the tunnel, while the Verkís company handled almost all of the design. This project was a milestone in Icelandic construction as it was the first private finance initiative without direct funding by the state treasury. It is also the only tunnel where tolls are charged. ==Safety issues== The Hvalfjörður Tunnel received a bad rating in the 2010 European tunnel test, which is carried out annually by the German automobile club ADAC. Different aspects were criticized and are also mentioned in the EuroTAP test (see external links), especially the weak lighting, absence of an automatic fire alarm system, too weak ventilation in case of a fire and a far distance to the next fire station (28 km). There are alcoves every 500m to facilitate turning around, and the storage capacity for water leakage is 2,000m3. Several improvements are announced for the next years. 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「Hvalfjörður Tunnel」の詳細全文を読む スポンサード リンク
