The bridges supported by high strength steel cables are the substitute to attain very lengthy bridge. Usually, cable supported bridge systems known as cable-stayed bridge and suspension bridge are used to achieve longer span bridge. In the cable-stayed bridge system better stiffness is achieved due to inclined stayed cables. In suspension bridge systems longer central span is achieved by provision of stiffened deck. The novelty in structural form, material technology and analysis methods offer further long span cable supported structural system. By combining the cable-stayed bridge and suspension bridge in a bridge, an innovative form of hybrid cable-stayed suspension bridge may offer enhanced behaviour. Mathematical model for innovative form of hybrid cable-stayed suspension bridge is addressed. The geometrical parameters play important role in structural behaviour of the cable-stayed suspension hybrid bridge. Nonlinear static analysis and modal analysis are carried out using SAP2000 software. The effects of intermediate side span support on the static and dynamic behaviour of cable-stayed suspension hybrid bridge are presented in the form of time period of bridge in lateral, longitudinal, vertical directions and pylon bending.
