Work has now begun on a section of the Route de Suisse as part of a three-year improvement plan. This first step which will last from 22 May to November 2017 will take place between the Chemin de Montfleury and the border between Geneva and Vaud. Several roads will be closed, new speed limits and diversions will be put in place. See illustration below. Also, see an interview by Nyon Région TV with the Mayor of Versoix here.
