This infrastructure project preparation concerns the regional competitiveness of the Vicenza, Padua and Rovigo provinces.
The Southward completion involves an interconnection with A4 Motorway to that with the S.S.n. 434 ” Transpolesana” (State Road), of about 52.8km.
The road alignment starts from the junction on the A4 Motorway (Milan-Venice), continuing on from the northern part of the same A31 Motorway (with the interchanges of Piovene Rocchette and Thiene). The centreline therefore has a north- south orientation and runs parallel to the layout of the S.S. n. 247 “Riviera Berica” as far as Noventa Vicentina. It then continues up to the tollgate of S. Margherita d’Adige – Megliadino S. Vitale extending south in direction of the S.S. n. 499, after having crossed the River Adige.
Among the major works, the project foresees the realization of an important bridge to cross the River Adige, between the towns of Piacenza d’Adige and Badia Polesine, and of some viaducts, for an overall length of approximately 4km, corresponding to about 95,000 sqm. of bridge decks.
The project envisages the realization of the following main viaducts, proceeding from North toward South: Torri di QUARTESOLO, 577.5m; River BACCHIGLIONE, 627m; River FRASSINE, 693m; SALETTO, 744m; River VAMPADORE, 165m; River FRATTA, 198m; River ADIGE, 992m.
Three tunnels are foreseen in the preliminary design, of which the first one, called Albettone Tunnel, is of traditional type and underpasses the Castellaro Mountain, while the other two, called Agugliaro and Saline tunnels, are of the “cut & cover” type.
