In an expressway bridge, when the bearing portion is damaged by an earthquake, a large level difference occurs on the road surface, repair construction difficult and taking time. Therefore, it is necessary to construct a prevent difference in levels difference in the bridge where a large level difference may occur on the road surface. However, it is difficult to construct the prevent difference in levels in the narrow space of the constructed bridge. Therefore, the authors have developed a simple prevent difference in levels that can be used without construction equipment.
