The planned closure of the Mont Blanc Tunnel between the Chamonix valley & the Aosta Valley comes into affect from the 2nd September at 5pm until the 16th December 5pm. This might affect those trekking on the TMB if they are trying to get to Courmayeur & back to Chamonix.
Any clients & their itineraries specifiaccly affected have been advised.
The only alternative would be to take a taxi around which would be long and expensive.
