Suspension bridge. A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 19th century. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
For the suspension bridge design, the main span was to be 1,750 feet, flanked by side spans of 719 feet. For the cantilever bridge design, the main span was also to be 1,750 feet, but was to be flanked by shorter side spans of 500 feet. Both bridges were to have mid-span clearances of 135 feet over mean high water. By 1922, Modjeski's suspension design was approved by the Delaware River Bridge Joint Commission.
