Seven emblematic mountain passes in the Hautes-Alpes are part of the "Grands cols" operation: Vars, Izoard, Noyer, Agnel, Lautaret, Galibier, and Granon. Recent work at the Col du Lautaret and Col Agnel emphasizes smoother traffic, respect for biodiversity, and careful aesthetic integration, featuring dry stone walls, larch wood and Corten steel furniture, signage, and reading tables.
At the Col du Lautaret, a major redevelopment completed this summer has reorganized traffic flow in this heavily frequented area. Parking has been consolidated, and degraded surfaces have been restored. The former departmental technical center was demolished to make way for the new "Vigie," a reception area with a sheltered space, restrooms, lockers, and an opening towards the Meije. This facility also guides visitors to the Jardin Alpin du Lautaret, the Refuge Napoléon, or tourist routes. These developments cost €3.6 million.
At the Col Agnel, the priority was to secure travel on a narrow road while preserving the natural environment. Work, which began in 2024 between 2,500 meters and the summit, had to adapt to snow conditions and high summer traffic. Parking was relocated to a less visible area to limit roadside stops. The summit section and the reception building with restrooms are nearing completion. A path will connect the Italian parking area to the pass. This operation, carried out with Italy, cost €600,000.
Since 2024, several other projects have been completed. At the Col de l'Izoard, the goal was also to reorganize parking and pedestrian flow while restoring natural spaces and biodiversity. A similar intention guided the work at the Col du Noyer, which lasted until spring 2026.
The operation continues with development projects for the Col du Granon, presented in June to elected officials from Val-des-Près and Saint-Chaffrey, and for the Col du Galibier. The overall financing for these works received €2.55 million in co-funding from Europe, the State, and the Region.
