The paper summarizes the results of recent ambient vibration tests and operational modal analyses carried out on the new curved cable-stayed bridge erected in the Commercial Harbour of Porto Marghera (Venice, Italy). The ambient vibration tests were carried out as a part of the reception tests of the bridge before its opening and included the recordings of the system response in selected points of deck, tower and stays due to either microtremors and wind or "simulated" traffic excitation. Full details on the experimental procedures, instrumentation, data analysis techniques and the dynamic characteristics obtained with output-only modal identification techniques are presented and discussed.
