# A412 motorway in Haute-Savoie: construction continues despite appeals

> On 27 October 2026, the civil liberties and detention judge ordered the A412 construction site in Haute-Savoie to be brought into compliance without suspending the work, following reports on the protection of beavers, amphibians and fish. The following day, some thirty farmers threatened with expropriation by the project between Thonon and Geneva expressed their distress. On 29 October, the Lyon administrative court of appeal rejected the application by the City of Geneva and associations to suspend the environmental authorization, allowing the construction site to continue.

## Reported figures

- 20 000 euros
- 40 millions d'euros

## Coverage angles

The three sides report the same judicial decision (compliance without suspension, then rejection of Geneva's application), but the left insists on environmental shortcomings and the lack of debate, the center highlights the procedure and the fate of opponents, while the right is not represented in the file.

**Common ground**

- The civil liberties and detention judge of Annecy orders the site to be brought into compliance under penalty without suspending the work
- The Lyon administrative court of appeal rejects the application by the City of Geneva and associations
- Failures to comply with environmental prescriptions are acknowledged
- The A412 construction site continues between Machilly and Thonon-les-Bains

**Differences**

- The left insists on failures in environmental monitoring of major projects, an angle absent from the center
- The center highlights the distress of farmers facing expropriation, little present on the left
- The left cites the City of Geneva's criticism of the lack of democratic debate, the center presenting the rejection mainly as a "setback for opponents"
