Alberg Pass Austria,

Arlberg Pass is a massif between Vorarlberg and Tyrol in Austria. The highest peak is the Valluga at 2,811 metres (9,222 ft). The name Arlberg derives from the tradition of the "Arlenburg", who are said to have once established themselves on the Tyrolean side of the Arlberg passes (1,793 m above sea level). Another story derives the name from the "Arlenbushes" that are very numerous there.[citation needed] Ski resorts at the Arlberg include Lech, Zürs, Stuben, St. Christoph, St. Anton, Oberlech, Stubenbach, Zug.
The name of the state of Vorarlberg is derived from the mountain Arlberg, which is located in front of the Arlberg, from the point of view of the Holy Roman Empire as well as the Swiss Confederation and the castle of the Habsburgs.
The old pass route was known since the 14th century in the form of a narrow mule track when people began to trade salt in the region. However, because the Arlberg was very poorly developed, for centuries people avoided the route and took detours over the Fern Pass or Immenstadt for trading. The development of the textile industry and of the postal service, however, led to the roads being surfaced in 1824.
With the rise of motor traffic in the 20th century, however, this became inadequate. It was decided that a 14-kilometre-long (9-mile) Arlberg Road Tunnel would be built between Langen and St. Anton. On July 5, 1974, the work began and the passage was opened to traffic on December 1, 1978. The tunnel has a toll; however, the old road over the pass is toll-free. A peculiarity of the tunnel is that it actually consists of two tunnels. On the Tyrolian side it is built over the Rosanna Gorge before the actual massif rises up in the direction of Vorarlberg over the tunnel
