This helps to stiffen the deck and reduce the tendency of the roadway to sway and ripple. Suspension bridges can easily cross distances between 2,000 and 7,000 feet (610 and 2,134 meters), enabling them to span distances beyond the scope of other bridge designs.

Suspension bridges are designed to be flexible. They will move vertically (up and down) and laterally (side to side, like a swing) to accommodate wind, change in temperature or load (the weights placed upon them). A suspension bridge that was not flexible would break very quickly!
