Great news since our post regarding the Tunnel du Chambon last month, is that a bypass tunnel has been proposed on this route – the RD1091 between Grenoble and the ski resorts of La Grave, Serre Chevalier and Briançon – and a temporary backup road is to be built in the meantime to aid local residents.

Our 2016/17 transfers from Grenoble will continue as planned, with quicker and cheaper transfers available to the area via Turin airport as detailed here.

The new tunnel will be 990 metres long, starting from the middle of the existing Tunnel du Chambon, next to Bourg d’Oisans – bypassing the collapsed area and creating a new route by digging into the slope. Completion is due for the 2016/17 winter season, at a cost of up to €25 million.

The 4km backup road – predominantly for local residents rather than a tourist route, and best avoided after heavy snowfall – is currently under construction on the left bank of the Lac du Chambon and is due for completion at the end of October this year. (The backup road is unlikely to cause further changes to our transfers for the 2016/17 winter season, but any related news regarding routes from Grenoble – or Turin – will be published on our web-site and social media.)

If you have any queries regarding your booking, our transfer times, prices or routes, you are welcome to contact us directly.
