Fontainebleau forest fires may keep France's 'Autoroute du Soleil' shut into the weekend
Fires in the forest of Fontainebleau south of Paris have forced the closure of the A6, the motorway nicknamed the 'Autoroute du Soleil,' and French authorities warned it may stay shut into the weekend, De Standaard reported on 25 July — hitting the busiest stretch of the summer holiday exodus.
The A6 is the primary route for the summer exodus toward southern France and the Mediterranean, so a multi-day closure during the late-July peak means significant delays, diversions and disrupted holiday journeys for large numbers of travellers — including the many families driving south from Belgium and the wider region.
The "Autoroute du Soleil" is the popular nickname for the A6 motorway from Paris toward Lyon, continuing as the A7 down the Rhône valley to the Mediterranean — the main route carrying summer holidaymakers from northern France and beyond toward the south coast and Spain. The forest of Fontainebleau is a large, historic woodland in the Seine-et-Marne department southeast of Paris, close to the town of Fontainebleau and its royal château. When fires broke out in that forest, the A6 running nearby was closed, according to De Standaard, at the peak of the French summer travel season.
Background
European summers have increasingly brought serious forest and wildland fires as heat and drought intensify, and France regularly battles blazes during July and August. The Autoroute du Soleil has long been synonymous with the French summer migration south, its name reflecting the millions who use it to reach the sun each year; disruption on this corridor during the grands départs is a recurring stress point for holiday traffic.
What to do
Travellers heading south through France in the coming days should check live traffic advisories, expect the A6 to be avoided in routing, allow extra time and prepare for diversions via alternative motorways.
