The world’s second deepest tunnel, the Mont-Blanc Tunnel, has recently reopened after undergoing three months of renovations. This tunnel, which links France and Italy beneath the Alps, underwent significant reconstruction work on a 600-meter stretch of the 11-kilometer structure. The closure was necessary for maintenance work, safety drills, and structural renovation, making it one of the first major European tunnels to undergo such deep renovations. Over 150 people were involved in the project, working around the clock for 15 weeks to complete the necessary upgrades.
The Mont-Blanc Tunnel, opened in 1965, is a key part of the north-south European route E25, running from the Hook of Holland down to Sicily. Situated 2,480 meters below the Aiguille du Midi summit, it is currently the world’s second deepest tunnel in operation. The recent closure was just one of many that have taken place throughout 2024 to ensure the safety and efficiency of the tunnel. Further renovation work is expected to continue in the coming years, with discussions between French and Italian authorities on whether to close the tunnel for a period of four years for a full refurbishment or carry out renovations over several decades with annual closures.
Even when the Mont-Blanc Tunnel is closed, alternative routes are available for travelers driving between France and Italy. These routes may add time to the journey but can save money compared to the tunnel tolls. The Fréjus Tunnel, located around 160 km south of the Mont-Blanc Tunnel, is a good alternative for heavy goods vehicles, connecting Modane in France to Bardonecchia in Italy. Other options include the Tunnel du Grand-Saint-Bernard, the Col du Petit-Saint-Bernard, the Col des Montets, the Tunnel des Montets, the Mont Cenis pass, and the Montgenèvre Pass. Each of these routes offers a scenic drive, though some may face closures due to heavy snow, so it’s essential to check the weather conditions before planning a journey.
Toll payment subscriptions, such as the TMB card and Eurotoll, cover multiple tunnels under the same pass, making it easier for frequent travelers to navigate the various routes between France and Italy. Multi-journey discount passes for tolls should be automatically extended to account for any closures or delays due to renovations or safety measures. While the Mont-Blanc Tunnel remains a popular and convenient route for travelers crossing the Alps, the availability of alternative routes provides flexibility and options for those looking to explore different scenic paths on their journey between the two countries.
For those planning a road trip through Europe in 2025, the reopening of the Mont-Blanc Tunnel offers a convenient option for traveling between France and Italy. The recent renovation work has improved the safety and efficiency of the tunnel, ensuring a smoother experience for drivers. While the closure had caused disruptions in travel plans, the availability of alternative routes allowed for continued access between the two countries. With ongoing discussions regarding further renovation works on the tunnel, travelers should stay informed about any potential closures or changes to the route in the coming years.
