The Tauern Autobahn (A 10) is an autobahn (motorway) in Austria. It starts at the Salzburg junction with the West Autobahn (A1), runs southwards, crosses the Tauern mountain range on the main chain of the Alps and leads to the Süd Autobahn (A2) and Karawanken Autobahn (A11) at Villach in Carinthia. The Tauern Autobahn is part of the European route E55 from Sweden to Greece, its southern section also of the E66 from Italy (South Tyrol) to Hungary. ==Course== It is long, of which are in 12 tunnels. The best known of these are the Tauern Tunnel and the Katschberg Tunnel that originally both had only a single bore, leading to chronic traffic congestions especially during summer holidays. The second bore of the Katschberg Tunnel opened in 2009, the second bore of the Tauern Tunnel in June 2011—after 35 years of traffic. From the West Autobahn junction at the Salzburg suburb of Wals-Siezenheim near the German border, the motorway runs southwards through the Salzach Valley between the Berchtesgaden Alps, with the Untersberg massif to the west and the Salzkammergut Mountains to the east. The first tunnel is at Golling in the southern Tennengau, where the Salzach breaks through the Tennengebirge. It passes Hohenwerfen Castle and reaches Bischofshofen in the Pongau district, then turns eastwards along the Salzburg Slate Alps to Eben and again southwards to Altenmarkt in the Enns Valley. From Flachau, the motorway climbs the northern slope of the Niedere Tauern range with the long Tauern Tunnel at an elevation of and runs through the Salzburg Lungau region to the toll plaza at Sankt Michael. From here it reaches Rennweg in Carinthia through the long Katschberg Tunnel, leading downhill from the Hohe Tauern range to Spittal in the Drava Valley. The southern section of the Tauern Autobahn runs southeastwards along the Drava between the Gurktal and Gailtal Alps to the Villach junction. In a variance to the general Austrian motorway speed limit of 130 km/h (81 mph), a special environmental speed limit of 110 km/h (68 mph) is in force on the Tauern Autobahn between 10:00 PM and 5:00 AM. 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 Autobahn」の詳細全文を読む スポンサード リンク
