The article is devoted to the issues of determining the deformed state of beam span structures of the road overpass during static and dynamic tests. The analysis of the operation of the superstructures of the road overpass with increased axial loads and vehicle speeds allows us to get a sufficient understanding of the causes of various types of deformation in structural elements. The result is all kinds of defects, violation of integrity and possible destruction of the structure, leading to an accident on a motor vehicle, which entails premature wear, large material losses and environmental damage. The indicators of the deformed state of the superstructure under test load indicate the operation of the superstructure as a single system in accordance with the design prerequisites.
