Indiano Bridge


Indiano Bridge is the first earth-anchored cable-stayed bridge in the world. It is a bridge across the Arno River in Florence .
The bridge was built between 1972 and 1978 by Società C.M.F. S.p.A. with architectural and urban architects Adriano Montemagni and Paolo Sica, and structural design engineer Fabrizio [de Miranda].
The project won the national competition organized by the Municipality of Florence in 1968, and immediately attracted attention because it involved a pedestrian bridge hanging below. For the structural characteristics Fabrizio de Miranda in 1978 received the European award-CECM ECCS. In fact it is the first cable-stayed bridge of large span anchored to the ground made the world and is one of the largest cable-stayed bridges in Italy of the twentieth century.
