Rhine

The Fleher Bridge, also bridge across the Rhine Dusseldorf - suppliant, between Dusseldorf and Neuss is a motorway bridge ( with pedestrian and cycle lanes parallel to the carriageways ) on the Rhine, the A 46 from the left-bank region ( Rhein-Kreis Neuss, Aachen region, district Heinberg, Belgium, Netherlands ) with the Bergisch Land (Wuppertal, Solingen, Hagen ) and the south of Düsseldorf connects. It also forms the southern part of the Düsseldorf motorway tangent quadrilateral and is named after the district suppliant of the city.

The building has three lanes and one emergency lane in each direction as well as the outside on both sides of a 2.75 -m-wide pedestrian and bike path. Not bridge crosses the Rhine at a right angle to protect the water catchment area of the old waterworks suppliant.

The Fleher bridge has the highest bridge pylon in Germany and the longest span cable-stayed bridges of all in Germany.

Construction

Characteristic of the Fleher Rhine bridge, a rampant center beam cable-stayed bridge is on the left bank of the Rhine standing 146.47 m high reinforced concrete pylon that looks like a twisted upside Ypsilon. In the stems of the pylon, a lift and a staircase are housed above the road. The stems are only 6.4 m wide bridge in longitudinal direction. They were made with a climbing formwork.

Has 368 m wide spanning main port on the Rhine a 41.7 m wide bridge deck of a 3 -cell steel box girder with a bottom plate width of 16.3 m and an orthotropic plate. This current bridge part superimposed on the right side of the Rhine on self-aligning bearings in a reinforced concrete building, which also leads on the local bank road.

The 13 - span approach bridge is a prestressed concrete structure with a length of 780 m and individual spans of 13 × 60 m. It consists of the superstructure to a length of nine fields from two unicellular girders, each with a 7.0 m wide at the base plate. The remaining four fields in the 240-meter range of Brückenabspannungen end at the pylon; they have a five cell box girder cross section with a bottom plate width of 29.5 m.

The steel superstructure and concrete bridge are connected to the pylon with a clamped into the pylon steel crossmember that a continuous beam overall system is created. The design height of the steel bridge deck as well as the pre-stressed concrete approach viaduct is a uniform 3.80 m.

History

The release of this bridge on November 3, 1979 meant a significant relief of the south of Düsseldorf from through traffic and a significant relief of the former South Bridge, which was the sole southern gate from the left side of the Rhine to Dusseldorf until then. At the same time it was a prerequisite for connecting the A46 to the west of the Rhine A 57

In 2003, it was found during an inspection that rust damage to the supporting cables were present and 9 of the 96 individual cables had to be replaced completely with their 325 individual wires. This measure is expected to cost a total of 9.5 million euros, at the same time, an improved anti-rust for about 7.5 million euros applied ( quote: " laymen would speak of a retread "). Work began in June 2006 and was completed for the Düsseldorf page until early 2010. The subsequent work on the Neuss side were finished in September 2010. The rope replacement cost about 9.2 million euros The next phase of construction, the renovation of the pylon stood on that was supposed to begin in autumn 2011. It was delayed because of the burnt in February 2012 highway bridge at Dormagen, its alternative route there was the Flehener bridge that reason could not be locked as planned. The renovation of the pylon was in April 2013 until the Bauvorbereitungsphase.

In October 2011, the contracts were awarded to work for improved noise protection, which was promised to the residents in 2010. By the end of 2012, a 1.50 high noise barrier was built. So could only be started with the further rehabilitation and the additional improvement of noise protection in March 2013, for until September 2013 [ deprecated] the roadway in the direction of Wuppertal is reduced to two lanes. Till then, there the expansion joint to be replaced, which was done in the other direction already in 2012. In addition, the repair of concrete planned, the sealing of the bridge and a coating with new asphalt.

On March 6, 2012, the district government, the city of Dusseldorf and the police agreed on the construction of a speed measuring system Vitronic on the bridge. End of May 2013 has gone to the noise protection of residents in suppliant in operation in the direction of Neuss a speed monitoring the restriction to 80 km / hr. The system sends the photos digitally to the clerk's office Dusseldorf. The city of Dusseldorf bears the costs for the construction of the plant. With the completion of the renovation work in the fall of 2013, the speed is also monitored in the direction of Dusseldorf. " Fame " attained this speed measurement equipment in winter 2013, when it became known that the software the speed camera was faulty and had to be adjusted a variety of administrative penalties.
