This research focuses on the development of polyester-rope suspended footbridges and consequently challenges the idea that modern versions of this bridge type must use steel cable. Characterization of the static and dynamic behavior of these bridges aids in determining which system parameters will influence future design guidelines for these structures and promote further construction.  Polyester’s low-weight and its high performance when wet also makes this material advantageous for temporary bridges that are rapidly deployed during flooding for rescue efforts and/or to repair walking networks.
