Tunnel du Mont-Blanc
Located on the French-Italian border, in the Alps mountain range, the Mont Blanc Vehicular Tunnel is one of the biggest construction works of the 20th century.
The tunnel opened on 19th July 1965. It’s 11.611 km (7.215 mi) long and links Chamonix (France) to Courmayeur in the Aosta Valley (Italy). It is one of the longest vehicular tunnels in the world. The road is called European route E25. It’s asphalted. It is not recommended if you suffer of claustrophobia. On March 24, 1999, 39 victims died in a fire which was started by a truck.
The tunnel is 8.6 m (28 ft) in width, and 4.35 m (14.3 ft) in height. It’s one of Europe's standout tunnels. The tunnel is subject to a toll. The minimum speed limit is 50km/h and the maximum speed limit is 70km/h. It is a single-bore, two-way tunnel. The elevation of the tunnel ranges from 1274m on French side to 1381m on Italian side, with maximum height of 1395.5 halfway through the tunnel.
