The Vizcaya Bridge ('Bizkaiko Zubia' in Basque and 'Puente de Vizcaya' in Spanish), is a transporter bridge that links the towns of Portugalete and Las Arenas (part of Getxo) in the Biscay province of Spain, crossing the mouth of the Nervion River. It is the world's oldest transporter bridge and was built in 1893, designed by Alberto Palacio, one of Gustave Eiffel's disciples. On July 13th of 2006 it was declared a World Heritage Site by UNESCO. The bridge, still in use, is 164 metres long and its gondola can transport six cars and several dozens of passengers in one minute and a half. It operates every eight minutes, 24 hours a day all year round, with different fares depending on the time of day, and is integrated into Bilbao's transport system. The same ticket used for the underground and bus systems can be used to cross the bridge. There is a new tourist lift installed in the 50 metre high pillars of the bridge that allows visitors to walk over the bridge's platform, from where the tourists can see the port and the Abra bay.
