Arch BridgeBeam BridgeSuspension BridgeCable-Stayed BridgesOne of the oldest types of bridges,arch bridges have great natural strength.Instead of pushing straight down,the weight of an arch bridge is carried outward along the curve of the arch to the supports at each end.These supports,called the abutments,carry the load and keep the ends of the bridge from spreading outward.When supporting its own weight and the weight of crossing traffic,every part of the arch is under compression.For this reason,arch bridges must be made of materials that are strong undSee more on pbsWhat Bridge Design Holds the Most Weight?
