The assessment procedure of a 90-years old, nailed steel Italian railway bridge, the Campasso Bridge, is discussed. The attention is focused on the material characterization, on the evaluation of the corrosion of the structural members and on the calibration of a structural model. The comparison of the results given by 1D, 2D and 3D models, compared to the outcomes of a load test, allowed the identification of a reliable structural model. On this basis, it is showed that the bridge can be re-opened to heavy commercial railway traffic provided only one of the rails is kept in service and provided few rehabilitation works are performed

Abstract
The assessment procedure of a 90-years old, nailed steel Italian railway bridge, the Campasso Bridge, is discussed. The attention is focused on the material characterization, on the evaluation of the corrosion of the structural members and on the calibration of a structural model. The comparison of the results given by 1D, 2D and 3D models, compared to the outcomes of a load test, allowed the identification of a reliable structural model. On this basis, it is showed that the bridge can be re-opened to heavy commercial railway traffic provided only one of the rails is kept in service and provided few rehabilitation works are performed
