The Kramer Tunnel in the Loisach Valley has been under construction as the longest road tunnel in Bavaria since 2019. It is part of the 5.6 km long bypass of the federal road B23 in Garmisch-Partenkirchen and is intended to contribute to relieving traffic congestion in the town, which currently has a traffic volume of approx. 25,000 vehicles per 24 hours. The construction of the Kramer Tunnel, which is approx. 3.6 km long, was carried out by means of conventional hard rock and soft rock excavation. The passage through a water-filled landslide area was a particular challenge during the work. During the excursion the entire tunnel and in particular the works for the construction of the inner lining and the carriageway can be visited.

Guiding is only available in German
