Stressed ribbon pedestrian bridges are most graceful, efficient and economical strains of suspension bridges. However, these structures have a major disadvantage – very large horizontal support reactions, which result mainly to the construction cost. In order to discover new forms and to extend the limits of stressed ribbon bridges, in the end of twentieth century these constructions were started to combine with other bearing elements in cable­stayed, under­deck cable­stayed bridges and other structures. At the beginning of the twenty­first century stressed ribbon supported on arch structure was discovered. The paper presents reviews of suspension supported on arch footbridges and classification. Considered the main geometrical design parameters and their interdependence. The paper presents a method of how to balance self­anchored suspension supported on arch bridge design computational scheme.
