Zarate-Brazo Largo Bridge


The Zarate-Brazo Largo Bridges are two identical cable-stayed road and railway bridges in Argentina, that crosses the Parana River (Parana Guazu and Parana de las Palmas) between the cities of Zarate, province of Buenos Aires, and Brazo Largo, province of Entre Rios.

The bridges have a suspended length of 550 metres , with a main span of 330 metres . Its pylons are 110 metres high, and its deck depth is 2.6 metres . They were built between 1972 and 1978 on design of italian engineer Fabrizio de Miranda, and rehabilitated in 1998. They are the first long span railway cable-stayed bridges in the world.

Zarate-Brazo Largo links the north of Buenos Aires with the southern part of the Argentine Mesopotamia, and also, by extension, Argentina with Uruguay and Brazil. The road link has four lanes. The main span is 50 metres over the water level of the Parana, which allows the pass of very large ships. It is one of only two such bridges over the Parana, the other being the more recent Rosario-Victoria Bridge (2003).
