INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
The bridge is cable-stayed in its midsection. It has a steel deck with a total width of 23.46 m, allowing for traffic flow in both directions, at a height of 50 m above sea level. The unsupported span between the central piers is 400.14 m, which at the time made it the world's second largest bridge of its kind. Between the central piers and the ground piers, there is a 147.42 m section on both sides, giving the central cable-stayed bridge a total length of 694.98 m. The deck is suspended with straight cables anchored to its edges, and to the heads of the central piers. The central piers, made of reinforced concrete, are 128.10 m above sea level and stand on foundations that extend 20 m below sea level, driven directly into the bedrock of the estuary.
The project was completed with two access viaducts, made up of two continuous box girders, on per each side, made of prestressed concrete. The total length of the viaducts is 863 metres.
The designers for the project were Florencio del Pozo, Fabrizio de Miranda and Alfredo Passaro. In 1979 it won the European Prize for Best Steel Construction.
