France traffic authorities warn of red‑alert congestion on July 25‑26 holiday weekend

Bison Futé classifies Friday, 24 July 2026, as orange for holiday‑bound traffic nationwide, and Saturday, 25 July, as red, indicating severe congestion on major routes such as the A6, A10, A11, A43 and A7. The agency recommends motorists avoid peak periods and, where possible, travel on Sunday, 26 July, which is rated green nationally. In the Sarthe, the A11 between Le Mans and Angers is expected to be heavily congested, with advice to use the A81 toward Rennes. In Auvergne‑Rhône‑Alpes, the A6 (Beaune‑Lyon), A7 (Lyon‑Orange), A43 (Chambéry‑Lyon) and A46 (Lyon‑east bypass) are singled out for avoidance during specific hours on Friday and Saturday. The region’s daytime traffic is orange on Friday and red on Saturday, while Sunday remains orange. Nationally, the A6 and A10 are highlighted as especially busy for departures, and Bison Futé urges drivers to consider the less‑congested Sunday. Separate road‑work notices for the Doubs department note night‑time resurfacing on RD 67, but do not alter the overall traffic warning.
