Egratz Viaduct resumes normal summer high season service


1 July 2013: Normal Service on Egratz Viaduct Resumes

Since the end of the winter, all traffic on the viaduct Egratz has been two-way. This was to allow route protection to be applied to the original road that hugs the mountain side. This route is vulnerable to rockfall and landslides.

Additional netting has been applied to prevent rockfall. There is still a risk of landslide. Large concrete blocks are being installed to prevent landslides. The work is not complete, but the authorities, aware of the high volume of summer traffic, have opened the route. This shall permit access and egress of traffic to the Chamonix Valley and the Mont Blanc Tunnel without hindrance.

Work is postponed and the old road has resumed its one-way, two lane, (descent) function. The Egratz is now used by traffic ascending the two lane viaduct, in the direction of Chamonix. 

In the event of heavy rainfall, expect the old road to be closed and two-directional traffic to resume on the Egratz.

From September 2, 2013 two way traffic on the Egratz will resume, so that route protection work may continue on the old road.
