Abstract: A full-scale highway bridge, in the process of being demolished and replaced was monitored using vibrational techniques in its in-service condition. The bottom flange and web of one fascia girder were incrementally cut and the vibrational monitoring repeated during the passage of a test vehicle. Comparison of some representative results are presented.
