Degradation characteristics of highway bridge condition rate was studied. Factors affecting degradation rate such as bridge type, member type, and environmental exposure were analyzed by using bridge condition data in Highway Bridge Management System. It can be drawn from the analysis that condition degradation rates are different from type to type of bridge member, and environmental exposure such as the amount of chloride used, the amount of snowfall can accelerate bridge condition degradation
