The Mont Blanc Tunnel closed until December 16
The reason for the closure is the complete reconstruction of two portions of the tunnel vault, each with a length of 300 metres.
The Mont Blanc Tunnel, linking Modane in France with Bardonecchia in Italy will be closed for 15 consecutive weeks, from 5:00 PM on Monday, September 2, until 5:00 PM on Monday, December 16. During this time traffic will be diverted along the alternative routes shown below: mainly along the A43 motorway, which runs from France to northern Italy through the Fréjus Tunnel, and along the Swiss A2 motorway through the Gotthard Road Tunnel.
