Museumsstück oder Verkehrsbauwerk - Aspekte zur Instandsetzung der Steinernen Brücke in Regensburg

摘要

The oldest usable stone arch bridge in Germany has been carefully repaired since 2010 and has been reopened for use in June 2018. Based on preliminary investigations and model repairs, the planning had to take into account, on the one hand, the building and transport requirements for an inner-city transport link. On the other hand, during the repair, the construction and ornamental elements had to be adequately preserved from the construction period between 1135 and 1146 to the first renovation phases to the destruction by war and traffic facilities. The article provides an overview of the preliminary investigations, the planning and their boundary conditions, as well as the resulting repair work on a still used transport structure, which is part of the monument ensemble of the historic old town. In the meantime, Regensburg is one of the UNESCO World Heritage Sites.
