Mont Blanc Tunnel: everything you need to know

Crossing the Alps to connect France to Italy, the Mont-Blanc Tunnel is one of the most famous road tunnels in the world. When it was inaugurated in 1965, its proportions made it the longest tunnel ever built. An engineering marvel, this impressive structure made it possible to shorten the journey between Chamonix and Courmayeur by 60 km. However, it was mainly to facilitate border crossing, which had hitherto been complicated by the winter closure of the Alpine passes, that it was built. The tunnel is also a solution of choice for heavy goods vehicles who want to go to the other side of the massif.

If you are wondering how long is the Mont-Blanc Tunnel? La Length of the Mont-Blanc Tunnel is 11.6 km. Located at an altitude of 1,274 meters, the opening on the French side is 5 km from Chamonix. On the Italian side, it reaches 1,381 meters and allows you to reach Courmayeur 5 km away.

After the fire that occurred in the tunnel on 24 March 1999, three years of repairs and safety work were necessary before it was reopened on 9 March 2002.

Practical information on Mont-Blanc Tunnel

Among the information you need to know before embarking on this crossing, the Mont Blanc Tunnel rates represent perhaps the most important point.

For a one-way departure from the French side in a car, it will cost you €46.30, while you will have to pay €57.80 for a return trip. If you want to spend less than seven days on the Italian slopes before returning to Chamonix, this type of rate for the Mont-Blanc tunnel will therefore prove to be much more advantageous.
