Arlberg road & rail tunnels to close 25 October for 400-person emergency drill, forcing detours over mountain pass

Austria’s motorway authority ASFINAG and state railway ÖBB will shut both the S16 Arlberg road tunnel and the parallel rail tunnel on Saturday, 25 October 2025, between 15:00 and 23:00 for a large-scale joint emergency exercise involving some 400 firefighters, medics, police and infrastructure staff. The announcement was released on 23 October to give logistics operators and travellers 48-hour notice.

The drill will simulate a multi-vehicle collision inside the 14-km road tube while maintenance crews are present in the adjacent rail bore, testing coordinated response, communication links and cross-tunnel evacuation procedures. Heavy trucks as well as private vehicles will be diverted over the Arlberg pass, adding roughly 30 km and significant elevation to the east-west trans-Alpine route that connects Tyrol and Vorarlberg.

For corporate mobility managers, the eight-hour closure threatens delivery schedules between Germany, Switzerland and western Austria. Time-sensitive consignments—particularly automotive parts and perishables—should be re-routed either overnight or via Germany’s A96/A14 corridor. Passenger transport providers must alert coach travellers to longer journey times and potential rest-time rule adjustments for drivers.

The exercise also affects ÖBB’s freight timetable; trains currently rerouted during ongoing rail-tunnel refurbishment will remain on alternative lines. Companies using combined road-rail solutions should double-check wagon slots and last-mile trucking windows. While the disruption is short-lived, lessons learned will feed into revised contingency plans due in early 2026, which could influence future tunnel-maintenance scheduling and insurance requirements.
