Bridges

He was the designer of several major works, including the first road cable-stayed bridges of large spans in the world, in the development of the railway system Zarate Brazo Largo, rivers Parana Guazu and Parana de las Palmas in Argentina (330m from center span in 1970- 77) and the first cable-stayed bridge in the world not self-anchored in the river Arno in Florence, locality Indiano (1972-78). Furthermore, he designed the cable-stayed bridge in the Rande Strait in Spain: at the time of its construction (1973-77) this bridge was one of the largest cable-stayed bridges in the world with central span of 400m and a board 2,40m tall.
