Project and construction
The idea of building a bridge over the Guadiana, which forms the international border between Spain and Portugal here, to replace the obsolete ferry, came up in the 1960s, so the governments of Portugal and Spain started negotiations to prepare a feasibility study bring to. The Spanish Dirección General de Carreteras and the Portuguese Junta Autónoma das Estradas began planning in 1963, construction began in 1985. The project was planned by the Portuguese engineer Jose Luis Cancio Martins and carried out by the companies Huarte SA from Spain and Teixeira Duarte from Portugal .
The main difficulties included the width of the river, which at this point is almost half a kilometer, and the depth of up to ten meters. 300 workers were involved in the four-year construction work; a total of 28,000 m³ of concrete and 5500 tons of steel were used. The international bridge was the reinforced concrete bridge with the second longest main span at the time of its construction. It was inaugurated in 1991.
Technical specifications
The bridge measures 666 m in length between the bridgeheads and is divided into five spans. The main span has a length of 324 m, the secondary spans measure 135 m. The carriageway is 20 m above the water level of the river, which allows larger ships to pass through. The two pillars, the shape of which corresponds to an inverted Y, rise 95 and 96 m respectively. The pylon, which is closer to the Spanish bank, was erected on an artificial island in the river, the other is on the Portuguese bank.
