SEPTEMBER-DECEMBER 2026 – TOTAL CLOSURES TO TRAFFIC

We would like to inform our customers that no extended autumn closure (of the kind carried out in 2023, 2024 and 2025) is planned for 2026 .
We would, however, like to point out that from mid-September onwards, numerous midweek night-time closures are scheduled (from Monday to Thursday, excluding any midweek French, Italian or Swiss public holidays). These closures will last 8 hours each (from 10.00 pm to 6.00 am), with the exception of 2 closures which will last longer (11/12 hours).
The schedule for these night-time closures is currently being reviewed by the Prefecture and will be published on our website and TMB Mobility app as soon as TMB GEIE receives approval to do so.
 
 
We invite you to check them regularly. There you will find all the latest updates, as well as real-time traffic information, webcam views of the two tunnel aprons and any closure notices.
