On the 27.10.2021 the Joint Venture Kramertunnel, BeMo tunneling and Subterra, completed the excavation of the 3.5km Kramer tunnel on the B23,  after 20 months of construction.

The breakthrough occurred in the upper cross-section area (dome) very close to the future ventilation structure at a depth of approx. 95 m - directly below the Kramer plateau. The Kramer tunnel is one of  5 tunnels which will relieve the residents of the Loisach river valley from through traffic:  Wank (in project, monotube and 3.5 km-long), Oberau (in construction, twin tube and 3.2 km long),  Auerberg (in project, twin tube and 2 km-long) and Farchant (already open for traffic, twin tube and 2.4 long) on the B2.
