During the construction the four current pillars of red sandstone built just so wide, that the line would have can be extended by a second track, what never happened. Rather, this possibility was instead later used to carry a road parallel the main. This was 1925 the railway bridge on the western halves of the pillars of the bridge shifted and 1941 then built a road bridge, which could get so only a roadway, on the eastern half. At the end of the second world war, the railway bridge destroyed by the retreating Wehrmacht, the road bridge severely damaged. Both were later rebuilt.
