France – Closure of the A6 and A126 Motorways

As part of its annual infrastructure maintenance program, the Île-de-France Roads Directorate (DiRIF), which manages the national road network in the Paris region, will carry out pavement renovation works on the A6 motorway, between Wissous and Évry-Lisses, and on the A126 motorway, between the municipalities of Champlan and Chilly-Mazarin in the Essonne department.

Due to these planned works, the A6 motorway (Paris to province direction) and the outer carriageway of the A126 will be closed along a 9 km section from Tuesday, July 15 at 11:00 a.m. until Friday, August 1 at 1:00 p.m., excluding weekends.

To minimize disruption for road users, the closures will only be in effect on weekdays.

To further reduce traffic disruption, diversion routes will be set up in both directions and clearly marked with special signage. Due to the risk of congestion, drivers are advised to avoid the area if possible during the works.

➡️ Detour from A6a/A6b toward Évry-Courcouronnes / Lyon:
Take the A10 toward Les Ulis, then continue along the N104 (outer ring road) to Évry-Courcouronnes, from where you can rejoin the A6.

➡️ Detour from A10 (province → Paris) toward Évry-Courcouronnes / Lyon:
◾ Continue on the A10 toward Paris,
◾ Exit onto A6b, then onto A86 toward Créteil,
◾ Exit at Rungis, return to the A86 toward Versailles, then take the A6b toward the province,
◾ Rejoin the main route via A10 and N104 (outer ring road).

Another phase of the project is scheduled for the autumn, this time in the province to Paris direction. The works will take place from October 20 to November 2, 2025, including weekends.
