The bridge 551 of the country road 232 Bad Bevensen – Altenmedingen leads across the Elbe – Seiten – Canal and was built in the beginning of the 1970s. It is a threebay prestressed concrete bridge with bearing distances of 32,05 – 66,40 – 32,05 m; as a result of manufacturing defects it has relatively severe flexures. Considering only the loading condition of dead load, the structure already shows bending cracks in the midspan.
