The Riesa Elbe Bridge is a 347 m long railway bridge and spans the Elbe in Riesa ( Saxony ) at river kilometer 108.39. The structure is on the Leipzig – Dresden railway line at 66.46 kilometers and in 1839 was one of the first large railway bridges in Germany.
Bridge from 1839
As part of the construction of the Leipzig-Dresden Railway , the construction of a combined road and railway bridge over the Elbe near Riesa began in August 1836. The 340 m long structure had eleven stone pillars that were founded on wooden post gratings. The superstructure consisted of wooden, curved girders below, which were connected to the road girders via St. Andrew's crosses. The construction was boarded so that it gave the impression of a stone vault bridge. In the river area there were six openings with clear widths of 28.24 m, on the left bank there were two arches, each with a clear width of 31.79 m. The structure was put into operation on April 7, 1839. The construction costs amounted to 270,000 thalers . During the German War in 1866, two bridge arches were destroyed by a fire set by Saxon troops.
Bridge from 1875
In 1874 the wooden superstructures were replaced with an iron structure. Separate bridge superstructures were installed on the old stone pillars for the two tracks and the road. When it was completed in November 1875, on the left bank of the Elbe, the bridge consisted of two stone vaults with a clear width of 13.0 m, followed by two 93 m spanning iron truss bridges with semi-parabolic girders and an underlying carriageway at the railway bridge over the Elbe . The road bridge had only one field with a 93 m span and three more lattice girder bridges with a 28 m span. The other six openings with their wooden superstructures remained unchanged. Due to the ice drift and flood that washed under a pillar, most of the new superstructures collapsed between February 19 and February 22, 1876. A wooden structure served as a makeshift bridge for the next two years.
Bridge from 1878
In the summer of 1876, the complete new construction of the bridge 30 m above the old bridge began according to plans by the secret finance councilor Claus Koepcke . The new bridge had four fields, one on Riesaer Ufer with a 44.4 m span and three with 101.4 m each. 8 m wide vaulted chambers were built as abutments. The separate superstructures of the double-track railway bridge and the road bridge had common pillars that were founded on iron caissons . Both bridges had, as a superstructure, iron, parabolic curved lattice girders with the carriageway below. The railway bridge was completed in February 1878 and the road bridge above in December. The construction costs amounted to 1.55 million marks.
On April 23, 1945 the road bridge was blown up and the railway bridge in the field on the left bank was badly damaged. Up until July 1, 1945, only the railway bridge was repaired. After dismantling a track and installing a plank covering, it was then also used by road traffic. With the commissioning of the new road bridge in 1956, the remaining track was moved to the center of the bridge.
Bridge from 1966
As part of the complete restoration of the double-track system and the electrification of the Leipzig – Dresden railway line, planning for a new railway bridge began after the road bridge had been built due to the insufficient stability of the almost 80-year-old bridge. In January 1964, work began on the fourth railway bridge in Riesa. It was completed in July 1966. The construction costs amounted to 16.8 million marks.
Since then, the steel structure has consisted of two sections, each with a three-span girder as a structural system in the longitudinal direction. The western part of the bridge is 195 m long and spans the shipping opening with an approximately 14.3 m high arched bridge in the middle field, the remaining fields are designed as trough bridges with approximately 3.4 m high main girders. The span of the western end span is 43.6 m, the main opening spans 101.4 m and the edge span has a span of 50.0 m. The subsequent three-span superstructure in the eastern foreland area is 151.6 m long. The smallest clearance height for the ships is 9.93 m at the highest navigable water level.
Except for the abutments , the old substructures were reused for the new superstructure, but two new intermediate pillars were built in the eastern foreland area. The new superstructure was built above the old bridge in the axis of the former road bridge and put into operation with one track. This was followed by the demolition of the old bridge and finally the transverse displacement of the new bridge by the distance between the two track axes.
Bridge from 2006
As part of the extension of the route to a third track, a further superstructure was built between 2004 and 2006 downstream next to the existing bridge on the existing pillars that were intended for this purpose from the beginning. This has the same geometry in the longitudinal direction as the construction from 1966. The new bridge, the space of which was already taken into account when the bridge was rebuilt after the Second World War, can be driven on at 160 km / h. A total of more than 21 million euros was invested in the third track.
2002 flood
The Elbe flood in 2002 had no effect on the stability of the railway bridge, but two viaducts ( 51 ° 19 ′ 7 ″ N , 13 ° 18 ′ 28 ″ E and 51 ° 19 ′ 16 ″ N , 13 ° 18 ′ 47 ″ E ) were in the eastern foreland between the Elbe and the Röderau Gleisdreieck destroyed.
