Part of the RD1091, between Briançon and Grenoble, will close for further work on Monday but re-opens on the 13th July for the Etape du Tour and the Tour de France.

As mentioned in our previous blog, the authorities did very well to open the Tunnel du Chambon for the busiest weeks of the winter here in Serre Chevalier and La Grave. However further improvement is required before the bike race this summer and hence the tunnel – just after the Les Deux Alpes turn off when driving from Grenoble on the RD1091 – will close again for several months from next week.

Don’t worry, we can still get you to your ski resort in comfort and safety via an alternative route, although it may take a little longer.

Affected routes on our airport transfers will include Grenoble to La Grave, Serre Chevalier, Briançon and Montgenèvre, and from Turin in the opposite direction to Les Deux Alpes and Alpe d’Huez.

Please speak to Emma or Jules at The Alpine Transfer Company if you are concerned about your airport transfer and how long it may possibly take via an alternative route.

You can call the office on +33 (0) 685 68 71 31 or send a Contact Form for further details.

We always recommend booking your transfer before confirming your flights, as we will be able to suggest the easiest and most cost-effective route for you (Turin is our recommended airport to reach Serre Chevalier and Montgenèvre).


The planned schedule for re-opening the Tunnel du Chambon is as follows:

  • Closed from 12 noon on Monday 6th March
  • Re-opens at 8am on Thursday 13th July until 9pm on Monday 24th July (Etape and the Tour de France)
  • Open from 5am until 9pm only between 24th July and 21st August
  • Closed from 12 noon on Monday 21st August to re-open on Thursday 21st December 2017

The really good news is that the Office de Tourisme tells us that the tunnel will be completely finished and operational for winter 2017/18.
