Mont Blanc Tunnel Closure

Mont Blanc Tunnel Closure
Starting from September 1st, 2025: complete closure for 15 consecutive weeks

The expiration date of all valid subscription passes (10 or 20 trips) as of the start of the full tunnel closure (September 1st, 2025) will be automatically extended by 4 months.
For example:

• a pass expiring on September 30, 2025 will be extended to January 31, 2026
• a pass expiring on April 30, 2027 will be extended to August 31, 2027, and so on.

The validity extension will be applied automatically. There is no need to submit a specific request for the extension.

As usual, if—approaching the new expiry date—the subscription hasn’t been fully used, it will be possible to retain the unused trips by reloading the pass (with 10 or 20 new trips).
In this case, both the unused and newly added trips can be used within 24 months from the date of the reload.
