The Metropolitan Expressway will serve as an emergency transportation route after a major earthquake, and will be equipped with a step prevention structure to prevent a large step from occurring on the road surface even if the bearing is damaged. Therefore, the height at which the step prevention structure was required was verified by a step running experiment. In this paper, we report the results and the installation policy.
