A transporter bridge that links the towns of Portugalete and Las Arenas, crossing the mouth of the Nervion River. People in the area, and even the official website, commonly call it the Puente Colgante (literally "hanging bridge", used for suspension bridge in Spanish), although its structure is quite different from a suspension bridge.It is the world's oldest transporter bridge and was built in 1893, designed by Alberto Palacio, one of Gustave Eiffel's disciples.
