The purpose of this study is to investigate the causes of corrosion of steel plate deck longitudinal U-ribs and to investigate the reinforcement method. It was confirmed that the corrosion of the longitudinal U-ribs occurred due to penetration water of the bolt hole of the shear key used in construction. The longitudinal U-ribs which were corroded were stiffened by attaching reinforcing plates, and finishing treatment was performed to prevent the surface water from flowing into the inside.
