N02 SECOND GOTTHARD TUBE - LOT 442 VALNIT BRIDGE

PIZZAROTTI SA was awarded, as a partner of the ‘Ponte Valnit’ Consortium formed with the companies Mancini & Marti and Ennio Ferrari SA, Lot 422 within the project ‘N02 Second Gotthard tube (2TG)’ for the new bridge at the Airolo junction in the Canton of Ticino.

The Valnit bridge will be approximately 250m long and the main structure will consist of a single-cell box girder deck in prestressed reinforced concrete.

The main span of the bridge, 96m long, will be built over the basin of the Azienda Elettrica Ticinese AET using the cantilever technique with successive segments cast in situ. The side spans, each about 50m long, will be built with traditional ribs. The bridge piers, approximately 16m high and in reinforced concrete, will be positioned on the north side.

The foundations will be deep, built with 1.5m-diameter drilled piles, sized according to geological and geotechnical analyses to ensure the stability of the structure and to manage interactions with the existing reservoir.

The project also includes the construction of modern offices for the client and construction management, strategically positioned to allow continuous supervision of operations. This project will significantly improve connectivity in the area, using advanced construction techniques and high quality materials.
