Vehicles rush to enter the tunnel before closure, creating short queues in the evening hours.
Night closures are planned by FEDRO (Federal Roads Office). During closures, traffic is diverted via San Bernardino. The Gotthard Pass is passable at night only if open.
Official diversion during night closures. The San Bernardino tunnel is open all night.
The night diversion is binary: when the tunnel is closed, the A13 San Bernardino is the only available motorway route. There is no queue threshold — closure is scheduled independently of traffic volume. If the Gotthard Pass is open and no night ban applies, it is also available as a scenic alternative.
