At the beginning of the 20th century a connection between the City of Salzburg and Untersberg was planned by means of a postless "monster cable-car". After 1945, after the stabilization of the economic conditions in Austria, the plan could be realized. In 1958 the Untersberg cable-car Society was founded, in 1959 construction started and in 1961 the opening followed.
The Untersberg cable-car (UBB) is operated by a two-cable system and runs in shuttle-traffic. The UBB, from a technical point of view, reaches several peak values in comparison to other cable-cars within the Alps: Exceptionally large difference in altitude of 1320 m, largest distance from the ground 286m, and an enormously long free-hanging span of 1.548 km between the valley station and post I.
