This paper presents the results of researches to developing the precast modular bridges. Procedures to decide types of bridges, results of the optimizations to minimize the cross sectional areas, concepts of joints between modules, and the results of the experimental tests to evaluate the performance of joints are presented in this paper. It is expected that the precast modular bridges may be the effective alternatives to rapidly replace deteriorated bridges and damaged bridges by disasters.
