Bizkaia

Puente Bizkaia – Portugalete and Las Arenas – Spain

The Bizkaia Bridge, opened on 28th July 1893, was the first transporter bridge in the world built with a metal structure. It stands at the mouth of the river Ibaizabal, at the point where the navigable estuary of Bilbao opened out to the sea up to the 19th century, and was designed for its great iron body to link the localities of Portugalete and Getxo, one of the banks steep and rocky and the other low and sandy. It has been listed as a UNESCO World Heritage Site since 2007.

History

The origins of the bridge date back to the end of the 19th century. The Bizkaia Bridge was built to link the two sides of the mouth of the Nervión without hindering shipping in one of the busiest river ports in Europe.

The design was the work of Alberto Palacio Elissague, also known for his part in the building of the crystal palace in the Retiro park in Madrid. The French engineer Ferdinand Joseph Arnodin took charge of construction, and the Bilbao textile magnate Santos López de Letona was the main backer and financier of the project.

An architect from Bizkaia province, Alberto de Palacio, assessed the different options available: gondolas, swing bridges of all kinds, lifting bridges, bascule bridges and so on. Finally, he ruled all of them out after technical analysis, before deciding on the invention he called the Palacio Transporter Bridge.

The Bizkaia Bridge was the brilliant result of combining two different technological innovations: modern suspension bridge engineering developed in the mid-19th century and large mechanical vehicles powered by steam engines. This meant it was hailed from the start as the triumphal arch of the new industrial civilisation.

Work began in 1890, and it was finally opened on 28th July 1893.
