The construction of the new axis is aimed at improving road safety, with the reduction of traffic crossing the Municipality of Samolaco, in Valchiavenna. The intervention concerns the construction of a new roadway with a length of about 3 km, with connection to the existing provincial roadway by means of two roundabout intersections. The road platform is characterized by an F2 section. The project has been subjected to a Regional VIA verification procedure. The road design was drawn up based on a LIDAR survey and return of the point cloud and DTM. The modeling if the new infrastructure was carried out by means of a BIM process, through which it was possible to evaluate in detail the minimum distance with respect to the MP gas pipeline and AT power line.
