Pier Luigi Nervi, bridge designer\ud

By M. Cresciani

Abstract

“A bridge is for an engineer what a dome is for an architect”.\ud The construction of a bridge is a central event in a professional life of an engineer. The symbolic value of\ud such a structure, at the same time functional and iconic, is one reason. Moreover, bridge represent the\ud perfect construction to test technological innovations, this can be seen by the fact that many pioneering\ud engineers linked their names to ground-breaking bridges: Maillart, Hennebique and in recent times,\ud Calatrava.\ud Pier Luigi Nervi, one of the most acknowledged engineer of the twentieth century, famously built many\ud domes but only one bridge, in Verona in 1965, he was 74. However, his interest for bridges was a constant\ud in his professional life. Furthermore, other Nervi’s structures, like the elevated motorway in Rome, La Via\ud Olimpica (1960) or even the suspended roof of the Burgo paper mill (1961) can be considered structurally\ud similar to bridges. This paper presents some of Nervi projects of bridges, from the early designs to the what\ud is generally considered his last effort, the Messina bridge. Particularly interesting are the discovery of two\ud projects for such structures recently discovered in the Archivio Nervi in Rome. Two images of these projects\ud are presented in this paper for the first time. They are just another evidence of the continuous investigation\ud on suspended structures of the Italian engineer
