Activists from the **Stop A412 Chablais** collective formed a human chain during a forest clearing operation on Friday, September 25, in the commune of Fessy in Haute-Savoie. The operation is part of the construction of a 16.5-kilometer toll highway intended to connect Thonon-les-Bains to Machilly in Haute-Savoie, managed by Amedea, a subsidiary of Eiffage. The activists, who have been mobilizing since the beginning of the construction work in early September, have faced systematic identity checks by gendarmes and several dozen arrests have occurred since the project started. Anne Granget, a horse breeder in the commune of Lully, whose land is heavily impacted by the construction site, provided the group with advice on identity checks and the potential consequences of arrests. During the walk to the site, activists discussed their concerns about the rapid pace of deforestation and the impact on the environment. They expressed frustration over the speed at which the machines were working and the limited means of action available to them. At the site, the activists formed a human chain and chanted slogans against the construction company. Despite the challenges, they remain determined, believing that as long as there is no asphalt, they have not lost the fight. The next day, September 26, a national mobilization day for the climate, brought some comfort to the activists, with a thousand people gathering in Machilly to support the cause. Nicole, a lifelong resident of the valley, expressed outrage over the "disregard for life and the laws" surrounding the project and advocated for developing the train network instead of building new roads. Sébi, a local musician, used his art to express opposition to the construction site, performing songs that highlight the importance of the forest and its wildlife. He had previously attempted to slow down the work by climbing onto a century-old oak, but was arrested after six hours of protest. Several legal challenges have been launched against the A412 construction site. The association **France Nature Environnement (FNE) 74**, alongside a dozen associations and forty residents, has requested the annulment of the environmental authorization granted by the prefect of Haute-Savoie on August 28, citing deficiencies in the impact study. Several individuals who may be expropriated to free their land for the construction site have also filed challenges within the expropriation procedure. According to La Tribune de Genève, the City of Geneva is also preparing a legal challenge against the construction site. Environmental protection associations are concerned about the slowness of the justice system in the face of the urgency on site. FNE 74 has noted that the concessionaire and the government appear to intend to complete the deforestation in urgency before the justice system has had the chance to rule, potentially ordering the suspension of work after mid-October. The environmental authorization allows deforestation from September 1 to October 31, and as of September 22, approximately 15 hectares of forest had already been cut down.
