Bridges are currently constructed and designed considering the structural safety required by the design code. However, coastal bridges are continuously deteriorated by many causes such as concrete spalling and exfoliation due to aging, faulty construction, and other deterioration factors. In this study, a prior ranking algorithm is investigated for performing maintenance management of coastal bridges and composed of more reasonable algorithm with studied on previous precedence priority ranking algorithm to realize bridge maintenance. With regard to a rating index of a total of 100 points, appearance defect index and load capacity deficiency was suggested with 40 and 60 point respectively. It is a more reasonable prior ranking algorithm that reflects the load capacity function, traffic of bridges and deteriorated bridge with high degree of deficiency point.
