During the period between January and March 2014, following a prolonged rainfall phase, a great landslide involved the slope along which the SS 19 "delle Calabrie" runs, leading progressively to the complete collapse of the whole road body. The Central Design Unit of ANAS, together with the regional unit, was appointed to design the reconstruction of this part of the road. So that, it was planned a geomorphological survey, completed with a site-investigation and a geophysical campaign, in order to completely define the evolution model of the slope. The geomorphological model identify both stratigraphic evidence and the fundamental role carried out by the lateral erosion of the Tanagro river. Starting from the geological and geomorphological model the reconstruction and stabilization measures were designed.
