Overview
- Friday’s departures are classified orange nationwide and red in Auvergne‑Rhône‑Alpes, with congestion expected from early afternoon into the evening.
- Major routes likely to be saturated include the A10, A11, RN165, A13, A7, A42, A43, A46, A47, A8, A9 and A50 toward the Atlantic, Normandy and the Mediterranean corridors.
- In Île‑de‑France, approaches to toll barriers could be difficult into the evening as holiday departures intersect with shopping traffic and regular commutes.
- Targeted advice includes avoiding Friday travel on the A7 between Lyon and Orange from 15:00 to 19:00 and between Orange and Narbonne from 14:00 to 18:00, with additional strain expected on the A43 from 17:00 to 20:00 and the A42 from 18:00 to 20:00, while return traffic may slow on the A1, A2, A25, A10, A11 and several Auvergne‑Rhône‑Alpes arteries including the A7, A41, A43, A46, A47 and A48.
- Saturday is forecast mostly green but with pressure in Île‑de‑France and Auvergne‑Rhône‑Alpes, notably on the A40, A43 and A46 and at Mont‑Blanc Tunnel access, and Sunday is projected green nationwide.
