It is considered results of tests of construction of bridge using standard mode of dynamic load – movement of automobile with different speeds. It is conducted analysis of registered signals of acceleration of vibrations, and also their spectra. It is described, that parameters of vibration of river and shore spans differ among themselves. Thus it is determined, that the considerable deviations from results of theoretical calculations, both on resonance frequency of vibrations and on dynamic coefficient, are fixed for river span of bridge construction.
