Curitiba cable stayed viaduct on Costruzioni Metalliche Magazine

Our project has been published on Costruzioni Metalliche, magazine born in 1949 and still the most representative structural magazine in Italy that promotes the culture and the technique of steel structures.

The project in subject crosses the main road that connects the international Airport of Curitiba, capital of Paraná State, in Brasil, to the city center. It has steel structure: the deck has multi-cellular box girder struc­ture, in steel-concrete composition. The tower, slanted and slender, is a steel orthotropic plate box structure.
