It aims also to improve the durability of new concrete bridge through applying the life prediction method of salt damaged bridges. As measuring chloride contents of these bridges on the southwest coastal area, it is shown that the average amount of chloride on these surfaces close to shore is 10.5 kg/㎥. This figure is much higher than that of the Standard Specification for Concrete(1.5 kg/㎥∼2.5 kg/㎥). In contrast, it is shown the average amount of chloride on these surfaces in tide zone is 13.1 kg/㎥. Its figure is much lower
