The Tauern Road Tunnel is located on the Tauern Autobahn (A10) in the Austrian federal state of Salzburg. The use is subject to a toll. With a length of (4.07 miles), the tunnel ranks as one of the longest frequently-travelled road tunnels in Austria. ==Construction== The tunnel crosses under the Radstadt Tauern range, part of the larger Low Tauern group. The nearby Radstädter Tauern Pass has historically been a possible crossing point of the main chain of the Alps. A first adit at a height of connecting the present-day states of Salzburg and Styria originates from medieval times when zinc, silver, cobalt and lead were mined here. A more exact dating of the drift in the zinc wall is not possible. The tunnel is only long and was made accessible by the Austrian Alpine Club. Planned as a two bore tunnel from the beginning, the first bore of the Tauern Road Tunnel was completed in 1975 with a total length of . Plans for the construction of the second, parallel tube were abandoned in 1988 and not resumed until the 1999 fire disaster (see below). Works began in July 2006, the second tube was completed on 30 April 2010, followed by a general refurbishment of the older first bore. The two-tube tunnel was officially opened with a ceremony on 30 June 2011.〔http://www.ita-aites.org/index.php?id=380&tx_ttnews%5Byear%5D=2010&tx_ttnews%5Bmonth%5D=06&tx_ttnews%5Bday%5D=22&tx_ttnews%5Btt_news%5D=1138&cHash=9379b7ef6053cf5101d35b429a02a01f〕〔http://www.focus.de/reisen/urlaubstipps/tauerntunnel-oesterreich-schneller-und-teurer-durch-das-nadeloehr_aid_641404.html〕 The northern entrance of the Tauern tunnels is in the municipality of Flachau in St. Johann im Pongau District (''Pongau'' region), while the southern entrance is in Zederhaus in the district of Tamsweg (''Lungau''). The Austrian Tauern Autobahn is an important north-south transport route through the Eastern Alps connecting Germany with Italy and Slovenia. In 2013, the average daily traffic passing the tunnel was about 18,000 vehicles, a quarter of which were large goods vehicles and trucks. The toll is 5.50 euros per car, a journey through the Tauern Tunnel and the adjacent Katschberg Tunnel costs 11 euro. The road tunnel should not be confused with the parallel Tauern Rail Tunnel which operates between Bad Gastein in Salzburg and Mallnitz in Carinthia, taking both standard rail passengers as well as car shuttle trains between the two locations. 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「Tauern Road Tunnel」の詳細全文を読む スポンサード リンク
