Overview
- Bison Futé has classified Saturday 18 July as red across France for departures, warning of very dense traffic from early morning into the evening.
- The agency lists high-risk routes and hours to avoid, including stretches of the A6, A7, A10, A75 and the Mont‑Blanc tunnel during midday and afternoon peaks.
- Authorities say the A6 has reopened after closures caused by forest fires near Fontainebleau, but they caution that local incidents could still change traffic forecasts.
- Traffic has already built into long tailbacks, with official counts showing several hundred kilometres of cumulative jams and a peak expected around midday.
- Bison Futé expects a clear improvement by Sunday with most of France back to green, while Bourgogne, the far east and Auvergne‑Rhône‑Alpes may remain busy.
