The San Bernardino tunnel in Switzerland, which lies on an important transit route (A13 Chur - Bellinzona), requires maintenance and restoration. On eleven nights, the 6.5-kilometre-long tunnel between Hinterrhein and San Bernardino will have to be completely closed.

The closures will take place almost exclusively during the week and will last from 10 p.m. to 5 a.m. each night. The tunnel will remain open during the nights from Friday to Saturday and from Saturday to Sunday. There will also be no nighttime closure on the night of October 31/November 1 (All Saints' Day is also a public holiday in Switzerland).

During the nighttime closures of the San Bernardino tunnel, the nearby San Bernardino Pass serves as a detour for motorists.

San Bernardino tunnel: Dates of the nighttime closures

Date Duration Time
November 2 to 3 1 night 10 p.m. to 5 a.m.
November 5 to 10 5 nights 10 p.m. to 5 a.m.
November 12 to 17 5 nights  10 p.m. to 5 a.m.

Alternate routes during nighttime closures

During the nighttime closures, the nearby San Bernardino Pass serves as a detour for motorists. However, driving on the pass requires a certain amount of experience. The maximum permissible vehicle width is 2.30 meters, the pass is unsuitable for caravans and due to weather conditions, it can also be temporarily closed at times. Please don’t forget to pay the mandatory toll fees on most Swiss roads.

The Gotthard A2 route provides a large-scale alternative route. The Gotthard tunnel remains open at night during the San Bernardino tunnel closures.
