Arlberg Pass, alt. 1,793 m, Alpine pass between Stanzertal Valley (Tyrol) and Klostertal Valley (Vorarlberg), watershed between the Danube and the Rhine, geological border between the northern limestone Alps and the central Alps. The 76 km Arlberg Road running from Landeck via St. Anton and the Arlberg pass to Bludenz is one of the highest mountain roads in Austria; used as a roadway since 1786, expanded 1822-1825. The Arlberg Road Tunnel reduces the length of the road by 3.7 km and the altitude by 475 m. The Arlberg-Bahn mountain railway (built by J. Lott 1880-1884, electrified in 1925) runs under the pass in a 10.3 km tunnel between St. Anton and Langen. The Arlberg region is an international winter sports area ( Arlberg Skiing Technique) with the St. Anton, St. Christoph, Zuers, Lech, Stuben and Langen ski areas. Passes in the Arlberg region: Flexen Pass and Hochtannberg Pass. Lake Spullersee with its power plant is also in the area. The Arlberg area represents the border of settlements and dialect between Bavarians and Alemanni. The name of the province of Vorarlberg is derived from the area ("Arlen" = dwarf pine).
