The Salierbrücke is a road bridge that spans the Rhine east of Speyer at river kilometer 399.80. The structure consists of a haunched steel girder bridge in the area of the river and a prestressed concrete girder bridge in the eastern foreland . It lies in the course of the federal highway 39 , which connects Speyer and Hockenheim .
The bridge train is a total of 595 m long and has two lanes as well as a walkway and a bike path on both sides.
Since January 21, 2019, the bridge has been closed to private motor traffic for renovation and upgrading. Only ambulances, buses, cyclists and pedestrians are allowed to pass the bridge during this time. The lockdown is expected to last until spring 2022.
history
Ferries
For centuries the Rhine at Speyer could only be crossed by ferry . There were five ferries in the vicinity of Speyer, all of which presumably existed long before they were first mentioned.
These were the ferry at Rheinsheim , first mentioned in 1191 , the Udenheim ferry (now Philippsburg ), first mentioned in 1297 , the Lußheimer Fahr to Altlußheim first mentioned at the end of the 13th century , the episcopal ferry near Ketsch first mentioned in 1228 and finally the Husener Fahr , first mentioned in 1296 the Rheinhausen ferry . A comparable ferry is mentioned in Bonn as early as 934.
In 1782, the Speyer cathedral chapter planned to set up a " flying bridge " instead of the Rheinhausen ferry (then called Rheinhauser Fahr) , but abandoned the plan because of the high costs.
Ship bridge
In a state treaty in 1862, the Grand Duchy of Baden and the Kingdom of Bavaria , to which the Palatinate on the left bank of the Rhine belonged at that time, agreed to build a ship bridge for road traffic near Speyer. The structure was built by the city of Speyer and commissioned in 1866.
In 1871, an agreement was reached between Baden and Bavaria to build the Heidelberg – Schwetzingen – Speyer railway with a ship bridge to cross the Rhine. The line was opened on December 10, 1873. The ship bridge was bought by the Palatinate Ludwig Railway Company from the city of Speyer and converted into a combined road and rail bridge. The structure had to be brought together several times a day for the passenger train on the Heidelberg – Speyer railway line and then moved apart again so that shipping traffic could pass on the river. In 1929 twelve trains crossed the bridge, which was meanwhile closed to traffic. The ship bridge had a length of 234.6 m and consisted of 43 pontoons. The width of the lane was 5.9 m.
Bridge from 1938
In 1925 the first negotiations between the German Reich , the Deutsche Reichsbahn-Gesellschaft and the states of Baden and Bavaria began to replace the ship bridges at Speyer and Maxau, which increasingly hindered the growing shipping traffic on the Rhine, with fixed bridges. Only in 1931 did the parties agree that the German Reich and the DRG would each bear 1/3 of the construction costs and the two countries each 1/6. The groundbreaking ceremony for the new Rhine crossing took place on September 23, 1933, but work on the combined road and rail bridge did not begin until mid-1935. The building was opened to traffic at the beginning of 1938, and the official inauguration followed on April 3, 1938. At the end of the Second World War , the bridge was blown up on March 23, 1945 by retreating German units.
construction
The bridge was 563 m long and 13.0 m wide. In the electricity area, it consisted of a two-field, postless strut framework construction made of steel with a roadway below. The spans of the continuous girder were 163.2 m and 108.8 m, the system height was 15.5 m with a main girder spacing of 12.8 m. In the foreland, solid wall girder structures were arranged with the roadway on top. On the right bank of the Rhine the structure had six openings with spans of 45 m, on the left bank of the river a field with a span of 20 m.
Pontoon bridge from 1945
From March 31, 1945, Allied pioneers began to build a pontoon bridge below the blown bridge . A two meter high memorial stone reminds of this on site. In addition, a ferry service was set up in early 1946.
Bridge from 1956
After the award in August 1954, construction of the new bridge began in early 1955, this time only as a road bridge, as the railway line had been closed. In order to unobtrusively integrate the bridge into the silhouette in the cityscape with the Speyer Cathedral , this time a deck bridge with an overhead carriageway was chosen as the bridge construction. On November 3, 1956, the building was opened to traffic by the then Federal Minister of Transport, Hans-Christoph Seebohm, and the Minister-President of Rhineland-Palatinate, Peter Altmeier . In the summer of 1977, the bridge was completely closed for road rehabilitation, as was largely the case from 2019 to probably 2022.
construction
The structure from 1956 is based on the foundations of the previous bridge, only the abutment on the left bank of the Rhine was moved westwards. In the foreland on the right bank of the Rhine, the bridge consists of a six-span prestressed concrete bridge with a length of 270 m and spans of 2 × 44.65 m - 2 × 45.15 m - 44.65 m - 45.75 m. The bridge superstructure has a four-web T- beam cross- section and is supported on the bank of the Rhine together with the main bridge on a wide granite-clad separating pillar. The gradient is 1.43%.
The river bridge is a three-span, haunched steel girder bridge with a length of 324.7 m, with spans of 109.2 m in the right bank of the Rhine, 163.5 m in the middle field and 52.0 m in the left bank of the Rhine. The construction height is 6.4 m above the main pillars, 3.37 m in the middle of the river and 3.0 m at the ends of the steel structure. The superstructure consists of a closed steel box with a width of 8.0 m, the upper deck cantilevered 3.1 m on both sides, cantilever beams are arranged every 5.25 m. In the current area, a clearance height of 9.1 m is maintained at the highest navigable water level.
