• Summary:- By the use of examples from the Authors' experience, various methods are shown of increasing the load capacity of major bridges, while keeping traffic flowing all or most of the time. These methods include refined calculations of loads and load factors, ''prestressing'' the hangers of a suspension bridge, altering load paths, converting a suspension bridge into a cable-stayed bridge,replacing the suspended structure of a suspension bridge, altering the steel grade of a suspension bridge, and making the roadway deck composite with the main structure.
