ATMB have announced that they will be resurfacing part of the A40 motorway, the Autoroute Blanche, between Passy & Sallanches this summer.
A 10km section of the road will be affected, on both sides between 26th June and 28th July 2017.
Work will be carried out on weekdays and not on weekends, so will no doubt cause delays for Geneva commuters.
