France–Italy: Tenda Tunnel closed until April 25. Carriers left without an official detour

The full closure of the Tenda Tunnel is another problem for transport companies operating between France and Italy. The lack of passage in both directions and the absence of an official detour mean that routes must be reorganized, transit times will increase, and operating costs will rise.

Drivers and carriers transporting goods between France and Italy are facing serious disruptions. In mid-April, the Tenda Tunnel was completely closed to traffic, with no possibility of passing through in either direction.

According to a statement from the Italian road authority ANAS, the tunnel remains closed
❌ from the night of April 12 to 13 (around 11:00 p.m.)
❌ until the morning of April 25 (around 6:00 a.m.)

During this period:
❌ traffic is suspended in both directions
❌ there is no possibility of passing through the tunnel at any time.

The closure is due to roadworks on the French side, including works on mountain access roads with numerous hairpin bends. The works are being carried out continuously and require a full closure of traffic.

The most important information for the TSL industry: ❗ no official detour has been designated. In practice, this means the need to reorganize routes and divert transport operations to other Alpine crossings. For many routes, especially local ones, this results in significantly longer journeys and higher operating costs. The Tenda Tunnel is one of the key road connections between south-eastern France and north-western Italy. It has been under reconstruction for years, which has regularly resulted in traffic restrictions and temporary closures. However, the current closure is one of the most severe in recent times.

❌ This is not the end of the disruptions. According to industry information, another full closure of the tunnel is planned for mid-September 2026. At this stage, a detailed work schedule has not yet been published.
