Overview

• Bison Futé has imposed orange-level alerts for Friday departures in northwest and southeast corridors, including key routes A1, A11 and RN165.
• Coastal corridors in the southeast and southwest and routes around Île-de-France are set for the most severe delays under red-level conditions.
• Return flows into Île-de-France from Spain via the A10 and through the Massif Central on the A20, A71 and A75 are expected to be particularly congested.
• The Mont-Blanc tunnel (RN205) will be heavily used for travel between Italy and France, contributing to localized bottlenecks.
• Traffic is forecast to return to normal levels by Monday, August 11, when vigilance warnings will be lifted.
