The Rudolf-Wissell-Bridge is part of the federal highway 100 (city ring Berlin). It was completed in 1961 and, at 932 meters, is the longest single bridge in the Berlin urban area.
history
In 1955, the Berlin Senate decided to build a city motorway to relieve the inner city area in view of the increasing car traffic. The city motorway was built in a north direction as an extension of the Halenseestrasse, which had existed since the 1930s, with the tunneling under the Rathenauplatz and the lanes in a trough parallel to the circular railway . The continuation to Wedding and towards Tegel Airport and beyond to the Berlin area required the construction of a bridge at a higher street level to cross the Spreeaue and the Berlin-Hamburger Bahn as well as the Berlin-Lehrter Bahn . The construction company Dywidag used the established in bridge prestressed concrete and the technology of cantilever construction . Pillar 9, which was completed first, rests on 153 concrete piles that were driven eleven meters deep into the muddy ground. It was the starting point for the free advance of the prestressed concrete box girders, which were guided over a total of six two-span frames. A few years after the bridge was put into operation, the columns in the double H shape ("double pier discs") turned out to be too weak and the structure had to be reinforced by adding vertical tendons . The curved eastern deck bridge also had to be reinforced laterally in the transverse direction. At the northern end of the bridge, the Charlottenburg motorway triangle connects with the A 111 and the Siemensdamm and Jakob-Kaiser-Platz exits . The length specifications for the bridge fluctuate between 928 and 960 meters due to the different reference sizes (inner radius, center or outer radius), as the two bridge parts form an almost 90-degree curve.
When it was inaugurated in 1961, the new bridge was initially called the Nordbogenbrücke, later it was named after the SPD politician and former Reich Labor Minister Rudolf Wissell .
A 1997 traffic census showed around 120,000 vehicles per day, an extraordinarily high level of pollution, which by 2005 had even risen to 220,000 vehicles. In 2017 it was 180,000 vehicles per day. In 2005, bridge construction specialists carried out thorough material investigations on behalf of the Senate Department for Urban Development in order to determine the stability and thus traffic safety. The removed drill cores and the direct measurements at various points on the bridge showed that extensive basic repairs are required to avoid a demolition. The expected renovation costs amount to eleven million euros. After further economic and technical investigations it was decided that this bridge should be completely renewed. The federal government bears the resulting costs.
New building
In January 2017, Deutsche Einheit Fernstraßenplanungs- und -bau GmbH (DEGES) launched an ideas competition across Europe on behalf of the Berlin Senate to plan the new replacement building . The new construction is particularly difficult because the bridge cannot be partially demolished due to its special design (e.g., as is often the case, only one lane at a time). In addition, the very narrow inner city location, the proximity of the Charlottenburg lock , a high-voltage line and Deutsche Bahn tracks for long-distance and local traffic make the new construction even more complicated. In 2017, DEGES and the Senate Administration held a competition for the new building with the main criterion of the least possible restrictions on ongoing traffic. In May 2018, the winning design by the engineering office Leonhardt, Andrä und Partner was presented to the public (which had already designed the new Reichstag dome and the structure of the Reichstag). The plans envisage that a new bridge structure will first be built east of the previous bridge. This will be 17.50 meters wide and will accommodate all previous traffic in both directions during the second construction phase. Then, at a distance of 60 meters, a second bridge superstructure will be built in place of the previous structure, which will enable the ailing bridge parts to be demolished as well as the new construction in small steps: large hollow steel bodies are placed on the old structure, which is stabilized with auxiliary supports . The old bridge elements are cut up under the girder structure and transported away. When everything has been removed, new bridge piers are created and the steel construction is lowered to their (lower) height. Concrete and asphalt then complete the second structure of the future two-part bridge. A renovation of the Charlottenburg triangle completes the adaptation to the traffic requirements of the 2010s. The estimated construction costs are 200 million euros . The new building is not expected to start until 2023 at the earliest .
