Traffic disturbances during CERN Open Days - 14 and 15 September

During CERN Open Days on 14 and 15 September between 70 000 and 80 000 visitors are expected.

For security reasons, the following roads will be closed:

  • Route de l’Europe
  • Route de la vie Chenaille in Echenevex between the D984C and the corner of route François Estier
  • Route de Meyrin from the roundabout by the French gates to route du Mandement
  • Route de Meyrin to Ferney Voltaire and its continuation into Switzerland, avenue Auguste-François Dubois, in the direction from France to Switzerland

Regular public transport lines will continue running but some of them may be heavily used by Open Days visitors.

We thank you for your understanding and hope to meet you at CERN Open Days.
