It is the world's oldest transporter bridge and was built in 1893, designed by Alberto Palacio, one of Gustave Eiffel’s disciples. The Engineer Ferdinand Joseph Arnodin was in charge, and it was the solution given by the engineer to the problem of connecting the towns of Portugalete and Getxo without disrupting the maritime traffic of the Port of Bilbao and without having to build a massive structure with long ramps, otherwise are 20km by car. Palacio wanted to design a bridge which could transport passengers and cargo, and that could allow ships to go through. The service was only interrupted once, for four years, during the Spanish Civil War, when the upper section was dynamited. From his house in Portugalete, Palacio saw his masterpiece partially destroyed just before his own death. On 1939-1941 it was rebuilt. HISTORY In 1999 important works were done on the bridge, including the installation of elevators in the towers of both banks and enabling a walkway on the upper beam, in order to introduce a tourist use. On July 13, 2006, the Vizcaya Bridge was declared a World Heritage Site by UNESCO At first, was painted black, however, a restoration project that includes a color change was approved in 2010. Three tones were proposed, similar to the three iron ore next to this place: -The ‘Campanil’ from Gallarta, the ‘Blenda’ from Triano and ‘Vena roja hematita’ from Somorrostro.
