Under concession company master contracts and the motorway investment plan, cofinanced by VINCI Autoroutes and the local authorities concerned, several interchange projects were completed or continued to improve service to the local region.
- On the A7, the new Vienne Sud half-interchange opened in December 2025, giving drivers direct access to the motorway towards Lyon (south-east France) and facilitating journeys between the greater Lyon area and the southern area of Vienne and neighbouring towns. It also improves mobility and user comfort with the creation of a carpool parking facility as well as new pedestrian walkways and cycle lanes. Each day, nearly 9,000 vehicles will thereby benefit from a more direct route, reducing congestion and improving safety on the secondary network.
- On the A7, works continued on the Salon Nord interchange, which is scheduled for completion in June 2026. Located to the north of Salon-de-Provence, the project involves building an additional half-interchange to improve motorway access and reduce traffic in the town centre.
- On the A7 between Chanas and Tain-l’Hermitage in south-east France, VINCI Autoroutes laid the first stone for the future Porte de DrômArdèche half-interchanges. Developed in partnership with local authorities, the project is designed to better connect this area, reduce congestion and facilitate access to the A7, as the road previously spanned 32 km across the Rhône valley without access between the two towns.
- On the A641, the A641/RD19 half-interchange project was completed at Oeyregave (south-west France). An entry and an exit slip road were added to the existing half-interchange, facilitating the connection between the RD19 and A641 for the surrounding region.
- On the A81, the environmental permit was granted for the future Grand Ouest interchange. Led by the greater Laval authorities, the Mayenne departmental council and VINCI Autoroutes, the future structure will connect the motorway, which is used each day by nearly 23,000 vehicles, to the future Parc Grand Ouest.
- On the A85, the Indre-et-Loire prefecture issued an environmental permit on 16 December 2025 for the project to build a half-interchange at Coteaux-sur-Loire. This new entry road will further boost the economy and tourism in the region.
