Bison futé forecasts a particularly busy weekend onÎle-de-France roads from Friday August 29 to Sunday August 31 , 2025. This last weekend of August marks the end of the school vacations and heralds the start of the new school year on September 1. In the Paris region, the first slowdowns will appear from early Friday afternoon on theA10 between Saint-Arnoult-en-Yvelines and Wissous, then on theA6 between Corbeil-Essonnes and Wissous. The combination of returning holidaymakers and commuters will make traffic difficult on the radial roads, theA86 and the Boulevard Périphérique.
The authorities recommend avoiding these routes during rush hour, and favoring public transport for travel in the Paris region. RATP and SNCF Connect offer alternative solutions using the metro, RER, Transilien and bus networks to get around traffic jams. The Bonjour RATP application calculates routes in real time according to traffic conditions.
The morning of Friday August 29 still looked passable, but the situation gradually deteriorated from 1pm onwards. Mass returns from the south of France, particularly from the Mediterranean arc via theA7,A8 andA9, converge on the capital. These flows combine with Friday evening business travel, creating congestion throughout the Paris region well into the evening.
Saturday August 30 is the most critical day according to Bison futé, which classifies this day as "particularly difficult" in the return direction. The first traffic jams are expected in the late morning on theA10 between Janvry and Wissous. In the afternoon, difficulties will intensify on all the radial roads leading to the gates of Paris. Traffic will remain heavy well into the evening, with journey times doubled or tripled on some stretches.
Bison futé's advice for this Saturday is clear: "reach or cross the Île-de-France region before 10am or after midnight". This recommendation is particularly pertinent for the last holidaymakers returning from the west of France. TheA11 between Nantes and Angers will be slowed down from 10am to 6pm, extending to Paris between 11am and 3pm.
Sunday August 31 will see an extension of the difficulties, with a gradual return to normal traffic levels in the evening. The A16, A25 and A13 will beparticularly busy with traffic returning from the north and west. In the Île-de-France region, theA10 andA6 will remain congested from late morning, with possible extensions into the evening.
Holidaymakers travelling from the south of France have several alternative routes to bypass the traffic jams in the Paris region. From theA6 in the Beaune area, we recommend turning onto theA31 towards Nancy, then in the Langres area taking theA5 towards Paris. This bypass avoids the traffic jams in the Val de Saône and enables you to reach the Paris region from the east.
For those coming from the west on theA10, the A19 is an excellent alternative. In the Courtenay area, turn off this freeway towards Sens, then take theA5 towards Troyes. This less busy route avoids the classic A10 traffic jams on the outskirts of Orléans. Drivers generally save 30 to 45 minutes on their journey time during busy periods.
The Francilienne (A104) bypass of Paris is a particularly efficient way of getting to the north or east of the region. This outer bypass avoids the Paris ring road, allowing drivers to cross theÎle-de-France region without passing through the city center. Motorists can also take theA86 for a closer bypass of Paris, although this solution remains more congested at peak times.
Optimum time slots remain decisive. Bison futé recommends "reaching or crossing the Île-de-France region before 11am or after midnight" on Fridays, and adopting similar times for the weekend. The 107.7 FM application broadcasts traffic information in real time, enabling you to adapt your itinerary according to traffic conditions. The Sytadin website also offers real-time mapping of traffic jams in the Paris region.
For families with children, we recommend regular breaks at freeway service areas, with water, snacks and activities to keep passengers occupied during slow-downs. This way, traffic constraints can be transformed into moments of family relaxation before the start of the new school year.
This period of heavy traffic reminds us of the importance of good travel planning. Between the alternative mobility solutions offered by public transport in the Paris region and the practical advice of Bison futé, every traveler can adapt his or her strategy for a more serene weekend. Anticipation remains the key word to avoid turning this last weekend of August into a source of stress before the start of the new school year.
