Railway overpass over Königstrasse (Hanover)

The railway overpass over Königstrasse in Hanover is a listed bridge for rail traffic of the Deutsche Bahn (DB). The long-distance routes of the east-west axis Berlin , Braunschweig , Ruhr area and Rhineland run over the building spanning Königstrasse as part of the east head of Hanover main station and to the south via Göttingen ; also the local public transport of the regional and the Hanover S-Bahn and the traffic to the Hanover depot of the DB. The railway overpass, which was built in the last quarter of the 19th century and later expanded, is due to be replaced by a new building after almost 140 years after almost 140 years from the beginning of April 2018, although parts of the technical monument in the list of cultural monuments of the state capital Hanover will be retained.

history

After the commissioning of the first railway line in the Kingdom of Hanover in 1843 between Hanover and Lehrte , rail traffic grew rapidly in the decades of industrialization . From the railway management building of the Royal Hanoverian State Railways , completed in 1863 on Joachimstrasse in Hanover , which had become part of the Prussian State Railways after the annexation of Hanover by Prussia in 1866 , an elongated pedestrian bridge ran parallel to Königstrasse on iron girders over the railway tracks. But road traffic still had to be secured on both sides with iron bars that had to be closed in front of the crossing trains.

For a further expansion of the up-and-coming city, the old freight station at Schiffgraben was first relocated, which, according to the " Latest Plan of the Royal Residence City of Hanover " from 1868, branched off the main line of the railway at Haasenstrasse . It was only relieved by the Hainholz marshalling yard, which went into operation in the same year , and then relocated to the product station for bulk goods opened in 1867 on Möhringsberg . The Weidendamm freight yard was finally put into operation for general cargo traffic .

In 1878 workers and engineers posed behind the scaffolding above the first segment arch of the railway overpass opposite the Prinzen-Halle, while the railroad tracks in the foreground were still at ground level; View from Augustenstrasse towards Thielenplatz and the Hannoverscher Fahnenfabrik

However, until the early years of the founding period of the German Empire , the railroad lines , which had been running at ground level , still severely hindered road traffic, especially between the former royal seat and its eastern city . It was not until 1875 and until 1881 that Hanover's inner-city railway systems were completely rebuilt: Among other things, a 4.50 meter high embankment was built in the urban area for a correspondingly increased track layout, which provided a total of 19 tunnels for barrier-free road traffic. This barrier-free construction measure was later known and imitated in the USA as the “Hanover System” or “Hanover System”.

In 1878 the first arch for the railway overpass at Thielenplatz was almost completed. The construction workers and engineers knew how to put their cylinders in the limelight for the desired snapshot of a photographer while they had already erected the wooden scaffolding for the second bridge section over Königstrasse. This created until the inauguration in 1880, a first transfer from Haustein , yellow Greppiner brick and sandstone - parapet , which has been adapted structurally over the course of more than 100 years the increasing rail traffic.

At the time of National Socialism , the Deutsche Reichsbahn acquired the former Tivoli entertainment establishment on the Königstrasse track in 1937 in order to be able to expand on its premises.

In 1960 and 1970 the bridge was widened by additions. The last time the EÜ was extended in 1998 as part of the S-Bahn construction for the World Exhibition Expo 2000 on the north side was a sliding trough.

Despite repeated maintenance work , the bridge could not be permanently protected from damage: Above all, penetrating moisture weakened the strength of the historical building materials against the continued increase in rail traffic. In addition to passers-by, this also endangers up to 11,000 cars a day that were determined during a count.

At the beginning of the 21st century, various options for maintaining the listed railway overpass on Königstrasse were considered. As a result, the Deutsche Bahn, in coordination with the Lower Monument Protection Authority of the state capital Hanover, decided instead of the overall more expensive maintenance measures to build a new bridge, which should then make the structure usable for another eight decades. According to the service and financing agreement of Deutsche Bahn, 23 million euros have been budgeted for the financing of the construction project.

The new overpass to be built will be constructed with the previous dimensions of the vault in reinforced concrete construction, which will, however, be placed on the original abutments from 1880. The existing masonry and reinforced concrete arches will be torn down and temporary bridges will be used over the railway tracks during the construction period.

The new reinforced concrete vault is first prefabricated in two parts on Thielenplatz and then pushed into its respective end position. The temporary bridges of the railway that have meanwhile been erected are dismantled again before insertion.

The plan is to secure the previous portal to Thielenplatz , which has shaped the cityscape, during the construction work and to rebuild it true to the original after the new bridge has been completed.

Reconstruction of the railway overpass, October 2018

During the renovation work in a total of six construction phases, during which Königstrasse between Augustenstrasse and Thielenplatz will be closed to traffic, a traffic concept was developed in cooperation with the state capital of Hanover and the SHP office and presented to residents and road users as well as political bodies at information events . The German Transport Science Society also presented the project on several dates in January 2017 with speakers from the regional project management of DB Netz AG in Hanover and the SHP engineers who are also based in Hanover. For long-distance traffic in north-south direction, the Laatzen exhibition center is used with a tram connection to Hanover main station. The temporarily affected S-Bahn traffic is temporarily replaced by the use of buses.

Insertion of the first segment of the new building on April 7, 2019

From June 2018 to around December 2019, the Königstraße underpass is closed to pedestrians and cyclists for around 100 meters between Augustenstraße and Thielenplatz. Even in the run-up to the closure of the underpass, several entrepreneurs who feared a slump in sales announced that they would give up their business premises in Königstrasse.

In October 2018, the old bridge was dismantled and auxiliary bridges were installed during a two-week closure of rail traffic. On April 7, 2019, after dismantling the auxiliary bridges, the first part of the bridge was pushed in and then the auxiliary bridges were re-installed in the missing part towards Thielenplatz.

The second part of the bridge was pushed in from 23 to 27 September 2019.

On October 11, 2019, the renewed bridge was opened to rail traffic as part of a ceremony. Individual traffic below the bridge should be possible in spring 2020.

The new building was completed on April 6, 2020 and the road beneath it was opened for private traffic again. The bus lines 100, 200, 128 and 134 run from that date also under the bridge.
