Abstract: After the collapse of the Carola Bridge in September 2024, similar bridges were subjected to special inspections. As a result, the Elbe bridge Bad Schandau was closed due to the detection of cracks and the use of susceptible to stress corrosion cracking prestressed steel. Extensive diagnostic and structural analyses were carried out, and comprehensive monitoring measures were installed to observe the behavior of the bridge and possible deterioration processes, including acoustic emission monitoring (AEM) and distributed fiber optic sensors (DFOS). A load test was carried out to evaluate the resistance of the bridge and to determine the remaining prestressing force. The structural reactions were recorded and evaluated. None of the limit criteria were reached during the test. The evaluation showed sufficient load-bearing capacity, so that the bridge could be approved for compensated traffic.
