Austmannali Tunnel

The Austmannali Tunnel (Austmannalitunnelen) is a road tunnel in Ullensvang Municipality in Vestland county, Norway. The 903 m long tunnel is part of the European route E134 highway as it goes up the Austmannlia mountain. The tunnel is located just south of the lake Valldalsvatnet, about 5 km northeast of the village of Røldal. The tunnel was built in 1982 to replace a steep section of the highway that was built in 1880 which had a road grade of 8.3% and included five sharp hairpin turns. The new tunnel is wider than the old road and it is one large horseshoe curve with a steady increase in elevation through the whole tunnel.

On 20 November 2009, there was a large rock slide and about 100 m3 of rock crushed the lower entrance area of the tunnel, completely blocking it. The concrete structure supporting the entrance was completely destroyed.
