The Vizcaya Bridge in Biscay, Spain connects the two towns of Portugalete and Las Arenas over the Ibaizabal River. The locals refer to the bridge as Puente Colgante, meaning suspension bridge, even though it is a transporter bridge, with a different structure. This bridge also happens to be the world’s oldest transporter bridge, as it was built in 1893. Its gondola can transport six cars, as well as passengers and cyclists.
