This study presented the analytical safety evaluation of precast modular bridge super-structure, using standardized modular members and robotic construction during the transportation routing and lifting conditions. In order to evaluate the safety performance of the bridge system, linear and nonlinear 3D full scale Finite Element (FE) for 12 m and 16 m standardized modular blocks was developed in ABAQUS and then analytical study was classified into two different structural systems according to steel girder structures: 1) modular bridge block lifting method including the steel girder system; 2) modular bridge block lifting method without the steel girder system. As a result, in analytical study, the results revealed that the maximum stress of each modular member was in maximum allowable stresses, during lifting condition. However, the stress concentration at the connected area was more critical in comparison to the behavior of entire modular blocks both 12 m and 16m, during lifting time.
