Recently, Ministry of Land Transport and Maritime Affairs (MLTM) of Korea has researched on the existing bridge management system (BMS) and its improvement. The current BMS for national road managed by MLTM was developed in late 1990's. However, its computational operating system was only changed but its performance and function have limited in simple function such as inventory and inspection data storage. For developing new BMS with the analysis of research trend, the research has been developing classified into the performance evaluation, the maintenance cost analysis and the decision making technique for optimal maintenance strategy and budget plan. The contents of research for establishing the advanced BMS combining asset management concept are summarized as follows; first, it may need life-cycle performance evaluation and estimation of the effect of maintenance interventions, and asset evaluation and its calculation technique related to maintenance cost. Second, decision making technology based on these various performances and cost related information is necessary for the life-cycle management of bridge. Finally, a proper computational system and practical education for applying a new method and system should be developed.
