The purpose of this study is to analyze the cause of corrosion associated with steel barrier wall corrosion, to review the current state of safety, and to describe the parts to consider in future design and maintenance.Also, when selecting the bridge type for the reduction of the long life and reducing the load, it is necessary to avoid the steel wall barrier of the entire cross-section of the barrier wall in the case of the steel plate type,I would like to discuss about reflection.
