The Herrenkrug railway bridge in Magdeburg-Herrenkrug spans the Elbe at river kilometer 329.56. The structure is part of the Berlin – Magdeburg railway line and was built between 1869 and 1872 when the railway line was re-routed as part of the new construction of Magdeburg Central Station . The bridge was put into operation on May 15, 1873.
Bridge from 1873
The 714 m long structure consisted of five main openings over the Stromelbe and Old Elbe, each with a span of 62.8 m, and in the west over the commercial port and in the east over the foreland of a total of ten secondary openings with a 31.4 m span. The double-track superstructures were girder bridges with steel lattice girders and an underlying carriageway and were designed as schwedl girders . It was one of the most important bridges over the Elbe on the east-west connections in rail traffic. In the 1910s, up to 125 pairs of trains used the structure every day. On April 18, 1945, the bridge was severely demolished by German troops. But already on March 12, 1946, the restored structure was opened to traffic after extensive construction work.
Bridge from 1979
In the mid-1970s, the railway bridge was replaced by a 680 m long new building, which was arranged parallel to the old bridge on the northern side. Over the Elbe, this consists of a postless, steel strut framework with a roadway below and the continuous beam as a structural system in the longitudinal direction. With a track spacing of 4.25 m, the tracks are fixed directly to the bridge substructure without a ballast bed. The structure has five openings and spans of 135.1 m in the middle field above the Stromelbe and 85.5 m in the remaining four side fields. The framework has a system height of 10.0 m with a node spacing of 9.5 m. The distance between the two vertical trusses is 9.7 m. The entire half-timbered superstructure is around 477.10 m long.
The eastern foreland is spanned with a deck bridge (length of the superstructure: approx. 204.94 m) and an incumbent roadway. In the longitudinal direction, this also has the continuous beam as a structural system with six fields, each with 33.6 m support width. On November 14, 1979, the new double-track building was put into operation. The maximum headroom is 6.14 m at the highest navigable water level.
The maximum speed on the bridge is 100 km / h.
On September 13, 1987, the bridge was damaged by the derailment of a wagon as a result of the slipped cargo from three cast rolls. This led to severe damage to a diagonal, which resulted in single-track train traffic on the bridge. The repair of the lower third of the diagonal by replacing two halves of the rod in sections took place within three shut-off breaks with a maximum duration of 16 hours.
After more than 40 years of intensive use, the Herrenkrug Bridge is to be completely closed from April to September 2021 so that the paintwork can be renewed and components can be replaced.
