In this study, the operational records of temporary bridges, definitions of temporary bridges, and applicable technical standards were reviewed, and these issues were clarified. The results of trial designs of emergency bridges show that the elimination of regulation of the deflection enables the rational design and construction of temporary bridges using readily available materials. In addition, the necessity of technological development for the design of structural details, clarification of performance requirements, and standardization of design is proposed to reduce the construction cost of temporary bridges and to speed up their construction.
