Mont Blanc Road TunnelIn 1965, the Mont Blanc seven-mile road tunnel opened, linking the countries of France and Italy. 11.6 km long, the Mont-Blanc tunnel links Courmayeur and the Italian Val d'Aoste with the French valley of Chamonix Mont-Blanc. It takes a little more than 10 minutes to go through the tunnel and 1/2 an hour overall to get from Courmayeur to the centre of Chamonix. The Mont-Blanc tunnel holds the world record for the deepest tunnel with 2480 m of rock covering it. It took six years, from 1959 to 1965, to bore the 11.6-km long tunnel.
