Zárate-Brazo Largo Bridge

Zárate-Brazo Largo Bridge

The Zárate-Brazo Largo Bridges are two cable-stayed road and railway bridges in Argentina, crossing the Paraná River (Paranà Guazù and Paranà de las Palmas) between the cities of Zárate, Buenos Aires Province, and Brazo Largo, Entre Ríos Province.

The bridges have a suspended length of convert|550|m|ft|0|lk=on|abbr=on, with a main span of convert|330|m|ft|0|abbr=on. Its pylons are convert|110|m|ft|0|abbr=on high, and its deck depth is convert|2.6|m|ft|1|abbr=on. They were built between 1972 and 1978 on a design by Italian engineer Fabrizio de Miranda, and rrefurbished in 1998.

Zárate-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 convert|50|m|ft|0|abbr=on over the water level of the Paraná, which allows the passage of very large ships. It is one of only two such bridges over the Paraná, the other being the more recent Rosario-Victoria Bridge (2003).
