A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
The 1915 Çanakkale Bridge on the Dardanelles strait in Turkey, connecting Europe and Asia, is the longest suspension bridge in the world.
The double-decked George Washington Bridge, connecting New York City to Bergen County, New Jersey, is the world's busiest suspension bridge, carrying 106 million vehicles annually.
