Each of the three tunnels will be closed for one night. The tunnels will be closed on the following dates:
The detour for the Kerenzerbergtunnel will lead over the lake route in the opposite direction. For the other two tunnels, the detour will go via the cantonal road.
Since there may also be changes, we recommend checking the current status before traveling.
