The construction of the viaduct on the Via Langhirano roundabout was a highly complex civil engineering intervention, carried out while maintaining heavy traffic throughout all construction phases. The work—a curved cast‑in‑place viaduct without intermediate joints— required rigorous execution planning, detailed work phases, and maximum attention to safety and timelines. The schedule was met thanks to the team’s expertise, constant support from site supervision, and effective coordination with the client.
