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 route runs under the Arganzuela and Tierno Galván parks, preventing congestion at the Nudo Sur. These works will free up traffic moving towards the Valencia highway (A-3) and to the east, avoiding traffic travelling to the Andalusia highway (A-4) between the Toledo highway (A-42) and the Avenida del Mediterráneo (A-3).
ACCIONA constructed the north tunnel of the south bypass using “Dulcinea”, the world’s largest EPB (Earth Pressure Balance) tunnel boring machine (at the time of construction) with a 15.62 metre diameter. The tunnel interior has three 3.50-metre lanes, 0.50 metre hard shoulders and 0.70 metre pavements.
