There are many iconic bridges throughout the world.
Some of them are also designed to allow safe access for shipping. Draw bridges and swing bridges are one way. Two bridges, eminently deserve inclusion on the list. They are both in Europe, one of recent construction whilst the other has been effectively a memorable feature for 123 years.
The Vizcaya transporter bridge: Getting there is half the fun?
In 1893, a disciple of Gustave Eiffel, Alberto Palacio, figured out another way: The transporter bridge. The Vizcaya Bridge in Bilbao, Spain is a suspension bridge built about 150 feet above the water, with a 36 wheeled cart that is pulled across. Hanging from it on 70 cables is a gondola that can carry freight and people; four million people and half a million cars use it every year.
When the gondola is out of the way, it can permit the passage of serious ships. Yet it takes up very little space on either shore.
