Cable Suspension Bridges
Cable suspension bridges come from South America, where the Inca originally weaved mountain grass and other vegetation. Oftentimes, these cables were as thick as a person’s body and able to hold a ton of weight. This helped them build suspension bridges longer than Europeans could ever think to build with stone. The goals of the bridges were both for offensive and defensive purposes. The only difference between the bridges during those bridges and modern-day bridges is that the main cables used in creating the walkway were also the cables to support them (Smithsonian Mag).
