Puente sobre el río Tevere

This bridge has a prestressed concrete deck, and the rest of the structure is ordinary reinforced concrete. It has three cantilevered spans. The central one is 58 m long, and the two lateral ones are each 51 m in length. The spanning structure includes several prestressed ribs, which were made at the workshop. As the ground was not sufficiently resistant, the foundations were built on piles, which have been placed both under the lateral and intermediate springers. The bridge has an overall width of 26 m. The pavement is separated into two independent carriageways by means of a central platform, which divides the traffic in opposite directions. The joints between the cantilevered sections of the arches, and the central girders, run diagonally to the plane of the deck. Thereby it is intended that differential settlements of the supporting bridge structure will not cause accidental cracking of the concrete.<br><br>Este puente lleva tablero de hormigón pretensado y el resto es de hormigón ordinario, presentando tres tramos, tipo cantilever, con 58 m de luz en el central, y dos laterales de 51 m de luz cada uno. La estructura que cierra cada tramo se compone de varios nervios pretensados, hormigonados en taller. Como el terreno no presentaba garantías suficientes de sustentación fue necesario el empleo de pilotes, tanto en las pilas como en los dos estribos. La anchura total del puente es de 26 m, quedando dividida la cálzala en dos partes independientes por un macizo central que encauza y separa el tráfico en dos direcciones. Las juntas achaflanadas existentes entre las dos extremidades—en contacto—de las ménsulas y de las vigas de cierre tienen la misión de evitar, en lo posible, el agrietamiento accidental del hormigón que pudieran ocasionar los asientos diferenciales en los soportes
