The present paper describes the maintenance methodology of deteriorating reinforced concrete piers supporting highway bridges. The highway network is considered, in order to plan the maintenance scheduling for many highway bridges. The Life Cycle Cost analysis with seismic risk is numerically carried out. The optimum maintenance plan is searched by GA. The numerical results show the maintenance plans for the scale of highway bridges, the elapsed years after construction, the seismic design level and so on. Also, it can be seen from the numerical consideration that the seismic strengthening for the bridge piers designed by former seismic design code is effective in the view of bridge management.
