The main aim was to identify the spectral characteristics of dynamic load of selected bridge structures and response from microtremor effect involved due to roadway and railway. For both types of bridges, the dominant frequency bands were identified which correspond to the natural frequency peaks in numerical model simulation. For all these case studies the frequency transfer (via spectral characteristics) and the vibration level decreases depending on the distance of the observed vibration source. These case studies showed certain dominant frequency bands for railway and for roadways.
