The whereabouts of the missing component of Dresden's Carola Bridge remain unknown. It was also not found during a sounding in the river by the Elbe Water and Shipping Authority (WSA) on Tuesday. According to the town hall, this revealed that the steel component, which weighs several tons, is not an obstacle in the riverbed for the possible passage of ships. If the steel joint is in the edge area, it is not detected by the measurement technology used, said Karsten Wild from the WSA. This only sends vertical signals downwards, which detect the zone directly below.
