The Muengsten Viaduct is an impressive steel structure connecting the cities of Solingen and Remscheid. After 120 years of use, the bridge showed damage and deviations from the standards, which made a fundamental renovation necessary for further use for the next 30 years. The structural recalculation was carried out by IWS Engineers, while PSP - Professor Sedlacek and Partners checked the calculation with RSTAB. Special attention was paid to compliance with the current design standards. The engineers have contributed significantly to maintaining the value of the structure.
