A XXL construction site in the mountains
Carried out in a constrained mountainous environment, this project met high technical, environmental, and seismic requirements. With a focus on combining technical performance and environmental responsibility, the operation also included the creation of three hibernaculums for reptiles as well as a pond for amphibians.
Inaugurated on November 24, 2025, the H2 avalanche gallery now secures access to the Principality of Andorra via the RN 320 and showcases Razel-Bec’s expertise in building complex structures in mountainous areas.
