In this article we discuss the construction of modular mobile overcrossing. Calculation of its constructive elements is performed and the optimum length of one module is determined. The purpose of the study is to develop a technique and calculate constructive elements of mobile bridge overcrossing in order to reduce traffic jams. Mathematical analysis, finite elements, finite differences and analytical method of displacements have been used in this study. The optimum length of each module of bridge overcrossing is received. The solution matrix of the method of finite differences allows us to calculate carriageway plate of the overcrossing with a wide variety of geometrical sizes, and also in case of different flexural stiffness properties of the plate and reinforcing elements. Calculation of the spatial frame of bridge overcrossing is performed by precise analytical method of relocation taking into account the bend and torsion of its elements.
