The main structures found along the route are:
1) Viaduct on the River Paglia: this is the main structure along the route and consists of a deck with three spans (70 m + 100 m +70 m) on load bearing steel beams tapered along their length to create low arched bays. Thanks to a precise hydraulic study, the structure is designed to withstand the bicentennial flood of the Paglia, as laid down in the Hydrogeological Structure Plan drawn up by the River Tiber basin authority.
2) A1 motorway underpass: the underpass will be built in stages, thus guaranteeing the continuity of the overlying motorway traffic during the work. The structure consists of a portal (with side walls made of piles and upper slab cast in situ) for the stretch located directly under the motorway roadbed, and "U"-shaped walls for the mouth sections.
