The aim of this research is to identify the effectiveness for maintenance works of bridge at northern area. In achieving the aim, the objectives are to determine the most defects that occur on the bridge and to identify the best approach by PWD to overcome defect at bridge. There are three case studies of bridges are located at northern area that have been chosen to support both of objectives to get the finding. The finding shows that the objective is achieved and the most defects that happened at the three of bridges are at expansion joint and pier. The defects that happen on the pier are on surface defect, crack, corrosion of steel, corrosion of reinforcement and wear/abrasion. For second objective, the finding shows that the PWD also have maintenance planning of bridge which is they carry out the inspection work of bridges for once in a year. They have three types of bridge inspection namely superficial inspection, principal inspection and special inspection. These types of inspection can help the improvement in maintenance management of bridge.
