Probably my favorite bridge ever is the Puente de Vizcaya/Puente Colgante/Bizkaiko Zubia that spans the Ibaizabal river/Nervión estuary in the Basque Country of Spain.
It’s actually the oldest transporter bridge in the world and one of the few that’s still functioning and transporting passengers to the other side of the river.
It opened in 1893, designed by Alberto Palacio, along with Ferdinand Amodin, both of whom studied under Gustave Eiffel, in order to connect the baths that were on both sides of the river so that the bourgeois who lived in the Getxo side of the river could also visit the baths on the working class side.
It was built with the transporter cables in the style it is so that ships and boats could pass through, as Bilbao was a capital of European shipbuilding and ironworking industry up until the 1970s or so.
It’s really an incredible monument, and it fascinates me every single time I go back to visit.
