The work presented in this paper focuses on durability of concrete bridges, which is worldwide concerned nowadays because concrete bridges will deteriorate and damage under the natural environment and the long-term usage. The shortage in bridges durability performance will result in severe environment problems; energy sources matters and economic issues. Quickly developed coastal cities and transportion, due to large-scale expansion of themselves and exploitation of ocean resource, have to face rigorous marine climate. Hence, the studies the authors have performed showed that as a civil engineer it is important to learn the research and countermeasure actuality on durability of coastal concrete bridges. According to current research, the existing problems as well as objectives for further studies are also indicated .
