Problems on a key route – Mont Blanc Tunnel to be closed at night
In April 2026, drivers using one of the most important routes between France and Italy should prepare for disruptions. The Mont Blanc Tunnel will be temporarily closed at night for several consecutive days.
A series of full night closures has been scheduled in April 2026 at the Mont Blanc Tunnel – one of the key road connections between France and Italy.
According to road authorities, the tunnel will be completely closed in both directions on the following dates:
❌ 13/14 April 2026 (Monday/Tuesday) – 22:00 – 06:00
❌ 14/15 April 2026 (Tuesday/Wednesday) – 22:00 – 06:00
❌ 15/16 April 2026 (Wednesday/Thursday) – 22:00 – 06:00
❌ 16/17 April 2026 (Thursday/Friday) – 22:00 – 06:00
The Mont Blanc Tunnel is one of the most important transport corridors connecting Western Europe with the southern part of the continent. Each closure, even at night, may lead to longer travel times, the need to choose alternative routes through other Alpine passes and tunnels, and local congestion on road infrastructure.
