Switzerland: A6 Simmenfluh Tunnel near Wimmis fully closed until 30 November 2026
The Simmenfluh Tunnel on the A6 near Wimmis in the Bernese Oberland remains completely closed in both directions until an expected date of November 30, 2026. The Federal Roads Office (FEDRO) closed the tunnel on June 24, 2026 for a multi-month comprehensive renovation. During this period, traffic is being routed via the parallel cantonal road.
This mainly affects access to the Simmental valley, for example towards Zweisimmen, Lenk and Gstaad. Anyone travelling there during the autumn school holidays should expect the detour and extra travel time.
What is being renovated in the tunnel
As part of the comprehensive renovation of the A6 between Thun-Süd and Spiez/Wimmis, FEDRO is renewing the electronic operating and safety equipment, including ventilation and incident detection, as well as the tunnel coating and the top layer of pavement. Because space in the tunnel is very limited, the work can only be carried out with a full closure. Long overnight closures were considered but rejected: they would have been more expensive and would have provided barely any usable working time per night.
Spiez–Wimmis ramp closed until November 12
In addition, the connection from Spiez to Wimmis via the Lattigen interchange is closed. Originally scheduled to end in late October, according to the latest information from October 12, 2026, the ramp is now expected to reopen on the evening of November 12. Traffic here is also being diverted via the cantonal road, putting extra strain on the roundabouts at the Spiez and Wimmis junctions.
Overnight closures in October and November
From 8 p.m. to 4:30 a.m., FEDRO will be closing further sections, with traffic diverted via the cantonal roads. The work is weather-dependent and will be postponed if conditions are unsuitable:
October 19/20 and 21/22: A6 between the Wimmis junction and the Lattigen interchange, each time in one direction only.
October 27/28 and 28/29: A8 between Faulensee and Spiez in both directions.
November 2/3 to 5/6: A6 between the Lattigen interchange and the Wimmis junction in both directions, followed by overnight closures between Spiez and Thun-Süd (November 9/10 to 12/13 towards Thun, November 16/17 to 19/20 towards Spiez).

Vignette and tolls in Switzerland
As on all Swiss motorways, the vignette for Switzerland applies on the A6 and A8. You do not need it on the cantonal roads used for the detour. Anyone continuing towards the Gotthard can find the current closures in the article on the Seelisberg Tunnel on the A2.
Switzerland toll at a glance
For cars, motorcycles and motorhomes up to 3.5 t GVW, the digital vignette requirement applies on motorways and expressways. Only an annual vignette is available, as Switzerland does not offer shorter validity periods.
For vehicles over 3.5 t GVW, the heavy vehicle charge (PSVA/LSVA) applies instead. In addition, individual tunnels (Great St. Bernard, Munt la Schera) charge a separate special toll, regardless of any other toll product. Switzerland has no distance-based kilometre toll.
