What is a suspension bridge? You might not be familiar with the terminology, but you've likely seen one before, if not in person then at least in photos or recordings. They're probably the most iconics bridges. Think the Brooklyn Bridge in New York City or the Golden Gate Bridge in San Francisco. They're the kind of bridges where the span (the part of the bridge for pedestrians and vehicles) is suspended in the air with the help of cables connected to towers. Suspension bridges are marvels of engineering and the following is a list of the 10 longest ones in the world.
