Results of the tests of aerodynamic stability of arched bridge in specialized wind tunnel are presented in this work. Atmospheric boundary layer properties were modeled in Landscape Wind tunnel of Krylov State Research Center to take into account wind characteristics – changing of mean wind velocity with height, turbulence intensity and spectrums. Present work includes two parts: visualization of flow structures behind the bridge deck and wind tunnel tests of modifications of original geometry to minimize oscillations due to vortex shedding. Tests with different modifications show that amplitudes were reduced at 50% on average or shifted in a region of high velocities.
