Comment le tunnel du Mont-Blanc est reconstruit à 2,480 mètres sous les Alpes

The Mont Blanc Tunnel, which connects France and Italy under the Alps, is one of Europe’s most vital infrastructure projects, carrying over 1.5 million vehicles annually. Opened in 1965, it suffered a devastating fire in 1999 but was rebuilt with advanced safety features. After decades of heavy use, the tunnel is now undergoing an 18-year renovation, including the reconstruction of the vault, improved ventilation, and the installation of state-of-the-art safety systems. This ambitious project aims to ensure the tunnel’s safety and efficiency while minimizing disruption to transport and trade between the two countries.
