The bridge maintenance strategy has been established for all bridges with long spans of more than 15m in Fukui prefecture. However, the deterioration characteristics of bridges are simply expressed in linear equations with small number of inspection data of bridges in the strategy. In this study, the deterioration transfer curves of each member elements of bridges in Fukui city and Fukui prefecture are introduced by using the inspection data. The deterioration transfer curve are classified with rapid, standard and slow velocity deteriorations. The deterioration characteristics of bridges are respectively discussed for bridges in Fukui city and Fukui prefecture. Furthermore, the deterioration characteristics of bridges of salt damage, frost damage environments and ASR suspected are also discussed.
