Stock Photo - 14 December 2021, Hessen, Wiesbaden: Work on the track bed and overhead lines is taking place on the railway line at the blown-up Salzbachtal bridge. The railway line was closed for months because the 300-metre-long motorway bridge over the Salzbachtal valley above it was in danger of collapsing. The bridge was blown up at the beginning of November. On December 22, trains between Mainz and Wiesbaden should be able to roll over the tracks again.
