Sao Paulo's landmark - the X-shaped concrete mast of Ponte Estaiadaの写真素材

The Octavio Frias de Oliveira bridge is a cable-stayed bridge in Sao Paulo, Brazil over the Pinheiros River, opened in May 2008. It is also known as "Ponte Estaiada" (the generic kind of bridge in Portuguese) and was conceived as a connection between Marginal Pinheiros to Jornalista Roberto Marinho Avenue, in the surroundings of Berrini Avenue, a fast-growing area of Sao Paulo, south area of the city."n"nDue to the similarity of an "X"letter, its monolithic concrete base is somehow unusual. Besides that, 'Estaiada' is the only bridge in the world that has two curved tracks supported by a single concrete mast.
