    Recently, according to the enlarged application of bridges and to increased service requirements of advanced moving vehicles on local loads, we have been concerned with maintenance of bridges. For the acquisition of serviceability in bridges during the service life, maintenance considered present conditions of bridges are very important rather than design or construction stages. Thus, the maintenance of bridges corresponding with total service life are have to estimate for reservation of safety and serviceability on existing bridges. Thus, the inspection, examination, and study about nationwide bridges have been performed for the bridge management system in Korea. In this study, in order to evaluate the damage conditions of bridges, inspection report about 50 bridges performed safety inspection test are applied. From the result of examination for damage conditions, main damages occurred in concrete members are to include the efflorescence caused by water leakage, and the shrinkages caused by poor construction. Especially, the cause of damages such as crack, deformation in bridges is subject to heavy vehicles which exceeds design load. In case damage was checked in main members, it is possible to take the place of general member not FCM(Fracture Critical Member), and it is possible to extend of serviceability by repair and reinforcement. This circumstance show us importance of recognition about deterioration problems and maintenance in bridges. Therefore, the purpose of this study is to evaluate the effective maintenance methods based on life cycle cost and to estimate the present conditions of bridges on local load in Kyonggi province.
