The Vizcaya Bridge, one of the most outstanding iron architectural constructions of the European industrial revolution, was hugely innovative due to the fact that it allowed the passage of ships on a wide estuary, with no need for ramps or for raising and lowering of the bridge. Today the Bridge is in a very good state of preservation and, as detailed, includes all essential elements of the original structure that define it as a working transporter bridge. AuthenticityThroughout its history, the Vizcaya Bridge has undergone partial updates and modernisations to meet the new necessities as they arose, with no detriment to the essential characteristics that lend it its value. In 2011, important engineering work was carried out on the Vizcaya Bridge to renew its interior and exterior structure. Since 1996, El Transbordador de Vizcaya S.L., a private company, has held the concession to manage the bridge, running until 2025 and giving work to some 30 people.
