Also known as the Puente del Campo Volantin, this graceful bridge is the work of Santiago Calatrava. Located in Bilbao Spain, the bridge is just a few meters from the Frank Gehry Guggenheim Bilbao. An improbable parobolic arch seemingly floating over the river, the bridge is best simply walked. Take a look. Also see the interesting Calatrava bridge in Valencia.
