The Brettfall tunnel leads under the rock protruding from the Larchkopf at the entrance to the Zillertal, on which the Maria Brettfall church is located, which also gave its name. The tunnel is part of the B 169  Zillertalstrasse  and the heart of the 3.2 km long bypass around Strass in the Zillertal , which was built to relieve the town of through traffic into the Zillertal. In the north, the tunnel is connected to Tiroler Straße  and the Wiesing / Achensee / Zillertal junction of the Inntal motorway without crossing , the road continues as the B 181  Achenseestraße  to Achensee . Most of the tunnel runs in the municipality of Strass, the south portal and a short section are in the municipality of Schlitters .
