The Lichtenberger Brücke is an eight-lane road bridge in Berlin on the B 1 / B 5 federal highways and crosses a large track area of the railway at Lichtenberg station over a length of around 137 meters .
First iron truss bridge
Around 1870, the construction of a bridge over the first railroad facilities ( Prussian Ostbahn and Lichtenberg marshalling yard ) was necessary for the purpose of crossing-free traffic with the routes. At that time, iron arch structures had proven their worth and so an approximately 50 meter long and 15.80 meter wide bridge was built from two iron arch segments with iron frameworks, held together by thousands of rivets (of which 11 meters wide for the carriageway, initially with large Paving stones was covered). The traffic on Fernstraße 1 was carried over this bridge , with the advent of electric trams in Berlin, later also tram line 69 and after the Second World War the trolleybus line 30. Directly on the bridge there were two car lanes in each direction and one track for the tram .
The first pavement was widened in 1913, followed by a comprehensive reconstruction around 1930 with the bridge being extended on both sides with reinforced steel girder structures and brick support structures.
Access to the Lichtenberg S-Bahn and long-distance station was possible either from Wenddorfstrasse or Weitlingstrasse through a tunnel-like mezzanine floor from the subway entrance or through a separate entrance building at the end of the bridge across from Skandinavische Strasse. The subway had separate entrances on both sides of the bridge.
The historic eastern section of the bridge
On the south side of Frankfurter Allee , right at the beginning of the bridge, stood the old station building, which was built in the neo-Gothic brick style. Below the sloping pedestrian path that led to the subway entrance, there were some dark red brick houses with official apartments for railway workers. With the demolition of the old iron bridge and the opening for Scandinavian Street, both the upper small station building and the railway workers' houses were demolished.
On the north side of the beginning of the bridge, Skandinavische Straße met the bridge on Frankfurter Allee, in which some small shops were located, including a. a shop that presented fresh fish in a large glass basin in the shop window, as well as a photographer's studio called "Photo Fisher". - The old houses from this time are still standing, but appear lowered compared to the new, higher street level. The large mural by the Nicaraguan artist Manuel García Moia is located on the tenement house on Scandinavian Street, the gable of which faces the bridge .
The historic western section of the bridge
On the south side, the tracks are widened because there was a marshalling yard here, and at the beginning of the railway era there were also locomotive sheds as well as coal bunkers and water systems. This is followed by the Deutsche Bahn AG and Deutsche Post AG premises (as far as behind Buchberger Strasse).
To the north of this end of the bridge there was a small kiosk on the bridge pillar, in which soft ice cream was offered in summer, "Ice cream Wibo" could be read on the gable. This was followed by three- to four-story residential buildings with numerous shops just a few meters from Frankfurter Allee, for example a café, a shoe shop, two jewelry and watch stores, a grocery store and a department store (the buildings described still exist, the stores have of course changed ). After the confluence with Siegfriedstrasse, there was then a driveway via Hubertusstrasse to the municipal Oskar-Ziethen-Hospital (today Sana-Klinikum, entrance relocated to Fanningerstrasse) and access to a much-used municipal bathtub and indoor pool, the Lichtenberg municipal swimming pool , also Hubertus -Bath called (closed for a few years).
During the construction of the new bridge, a historic milestone was moved to the driveway (out of town), which is right next to the stairs leading to the train station.
Planning and start of construction for a new bridge
The old iron bridge soon became a real bottleneck due to the rapidly growing traffic, so from 1968 to 1970 plans were made for the construction of a large, multi-lane bridge. Together with the also planned car tunnel under the intersection of Am Tierpark / Straße der Befreiung (today again Alt-Friedrichsfelde), this was part of the so-called Ostradiale and, according to the Berlin economic plan in 1970, was called Verkehrslösung Lichtenberg .
In 1972/73 work began on the new bridge without demolishing the old bridge because the entire street had to be relocated more south. At the same time, the access to Lichtenberg train station was changed, that is, the separate entrance building was demolished and Skandinavische Straße was lowered, which could be led under the eastern section of the new, much longer bridge and joins the former Wenddorfstraße. The resulting extension of the new Lichtenberger Bridge is called the Scandinavian Bridge . The Scandinavian Road was given its own bridge trailers for this purpose, which can be clearly recognized through the metal covers when driving or walking over both bridges.
The construction work was carried out jointly by the civil engineering combine Berlin and the VEB Autobahnbaukombinat , Magdeburg branch, around 400 specialists were deployed.
New steel and concrete construction
The new bridge was made of steel and concrete using girders and five closed box girders and provided with a steel lightweight carriageway construction, it consists of two separate parts. The bridge loads were supported not only on the abutments but also on the subway tunnel, for which this was specially reinforced. The bridge now has four lanes in each direction of travel, is 42 meters wide and 130 or 143 meters long (different lengths because it goes diagonally over the railway systems). There are 4.7 meters wide sidewalks on both sides. The tram route has been changed (relocation over Herzbergstrasse - Rhinstrasse) or the route shortened so that no trams can cross the new bridge.
The ceremonial handover of the first completed southern part of the bridge to traffic took place on December 19, 1975. The expansion of the second, northern half of the bridge lasted until October 7, 1977. In December 1977, work began on demolishing the old iron truss bridge, which until then had been used for pedestrians. After the bridge structures had been carefully removed, the substructures (pillars and abutments) were finally removed by blasting.
The Lichtenberg district office states on its website construction times between 1978 and 1982, which is wrong for the actual bridge construction time. However, it can be explained by the fact that this information refers to the following construction work such as the completion of all connecting roads, the construction of the new station building, the connection of Scandinavian Street to Weitlingstraße and the removal of the old iron structure.
Soon after 1990 the new massive bridge proved to be no longer able to cope with the rapidly growing traffic (a rough count had resulted in around 4,000 cars per hour and direction of travel) and above all the heavy load requirements in the now reunified Berlin. A comprehensive renovation (focus: renewal and reconstruction of the protective and bridge railings, concrete replacement and protective measures, renewal of all bridge bearings, renewal of the chamber walls, steel construction work with cornice elevation and road edge change, renewal of the drainage pipes, corrosion protection hollow box north, sealing, crack grouting) with a renewal of the Road construction on both sides was commissioned by the Senate Building Department and carried out in 2001/2002, the costs amounted to 7.4 million marks.
