Brandbergtunnel, Road tunnel in Zillertal, Austria
Brandbergtunnel is a road passage through the Zillertal region of Tyrol that links Mayrhofen-Laubichl with Brandberg. The roughly 2.1 kilometer tunnel cuts directly through Alpine rock to create a straight route across the mountain terrain.
Tauernkraftwerke AG started construction in 1976 to provide access to the Zillergründl dam building site in the Austrian Alps. The project became part of the region's water power development efforts.
The tunnel represents a significant milestone in Austrian alpine engineering, demonstrating the integration of transportation infrastructure within mountain landscapes.
Drivers can use the tunnel to cross Zillertal without detouring through Mayrhofen town. The route demands attention due to the steep gradient as it climbs through the mountain passage.
The tunnel stands out for its unusually steep gradient compared to typical road tunnels. This technical feature makes it a notable example of mountain construction adapted to extreme Alpine conditions.
