The bridge galloping in the air flow is studied experimentally. The elastic suspension allows the model to oscillate with six degrees of freedom. However, only two modes of oscillations are observed in the experiment. One of the modes is a translational oscillation in the vertical direction. In the second mode, translational and rotational oscillations occur. When the velocity of the incoming flow increases, the bridge model enters two different oscillation modes sequentially. Oscillations occur at small positive angles of attack. The velocity ranges in which there are oscillations, depend on the angle of attack of the incoming flow.
