The Indiano Bridge (also Viadotto dell'Indiano ; German about: bridging the Indians , Viaduct of the Indian ) is a road bridge over the Arno in Florence , in the course of a longer high road to the airport Amerigo Vespucci to the north of the Arno with the expressway connects to Pisa and Livorno , the so-called FI-PI-LI south of the Arno.
Location, name
The Ponte all'Indiano is located at the confluence of the Mugnone in the Arno, which forms the western end of the Parco delle Cascine . At the end of the park stands the Monumento all'Indiano in memory of the Indian Prince Rajaram Chuttraputti , Maharajah of Kolhapur , who suddenly died in Florence in 1870 at the age of 21 on his way back from London , where he wanted to pay his respects to Queen Victoria . The bridge, almost 100 m away, was named after the now well-known name of the monument, also in honor of the Indian .
description
The Ponte all'Indiano is a cable-stayed bridge that leads a four-lane expressway over the Arno and two riverside paths. In the north it crosses another bridge over several railway tracks, which is followed by the elevated road leading to Amerigo Vespucci airport . In the south, the actual cable-stayed bridge is extended by a long foreland bridge over the flood bed of the Arno.
The Ponte all'Indiano is one of the few bridges with two steel pylons arranged in the central axis , which are slightly inclined outwards. The outer stay cables of the bridge are, unlike usual, anchored in anchor blocks in the ground, while the inner stay cables carry the 206 m long bridge deck. The two directional lanes pass the pylons separately from one another.
The roadway girder is a total of 22.4 m wide and consists of two beveled steel hollow boxes , which are stiffened over the open central axis by horizontal lattice girders . These hollow boxes carry the outwardly protruding steel plates of the directional lanes. While the directional lanes only have the two lanes, but no hard shoulder or sidewalks, a separate pedestrian bridge hangs under the open central field. At the pylons it is connected to the riverside paths via flat ramps.
Shortly in front of the pylons there are double concrete pillars that support both the steel deck girder above the main opening and the bridge structures for the two further lanes that are separated from there. The road girders each consist of a pre-stressed concrete slab on two steel solid wall girders , which are stiffened by diagonal struts and supported by concrete pillars approximately every 35 m.
The Ponte all'Indiano was planned by the bridge engineer Fabrizio de Miranda together with the architects Adriano Montemagni and Paolo Sica, who won a competition of the city of Florence with their design in 1968. The bridge was built by Costruzioni Metalliche Finsider between 1972 and 1978 .
