Mont Blanc Tunnel

The Mont Blanc Tunnel has published the provisional schedule of planned closures for the period January–August 2026, scheduled for safety drills and maintenance works.

Traffic interruptions are generally planned during night-time hours. Maintenance activities that do not require a full tunnel closure are also scheduled and managed under a alternating one-way traffic system, according to predefined time slots.

Please note that the published schedule is provisional and may be subject to changes.
An updated version is continuously available via the QR Code included in the document, on the TMB Mobility app, and on the official website:
