Cable-stayed bridge more cables to ensure greater economy. Cable-stayed bridges may appear to be similar to suspension bridges, but in fact, they are quite different in principle and in their construction. In suspension bridges, large main cables (normally two) hang between the towers and are anchored at each end to the ground. This can be difficult to implement when ground conditions are poor.
