The Rohrdammbrücke is a traffic structure built in connection with the expansion of the Siemens factory complex in the Berlin district of Spandau to cross the Spree . It is the only road bridge over the Spree in the Spandau area. Today's bridge was built in 1953 in place of the Rohrdammsteg built here in 1905 , which was also called Siemenssteig .
history
The Siemens company had 1900 on a previously undeveloped area late 19th century, a complete town create, included both plants as well as residential buildings for workers. The workforce, which at times consisted of several thousand people, was also recruited from Berlin's inner city districts. From there, the Siemens workers came either on foot, by bike across Nonnendamm , by barge on the Spree or by ferry across the Spree from Fürstenbrunn train station or by train via the ring stations. A river crossing on foot was urgently required, for which a connection between the Fürstenbrunn train station and the southern end of the Rohrdamm was an option. The responsible authorities from four authorities (city administration Charlottenburg, city administration Spandau, Prussian hydraulic engineering administration, city administration Berlin) should have given their approval for this construction project. Apart from the usual delays in the coordination between the authorities, the city of Charlottenburg was not interested in promoting the Siemensstadt production site (until 1914: Nonnendamm colony) because they feared a loss of tax revenue. The company management had their "chief planner" Karl Janisch design a quickly mountable Spree crossing. According to these plans the bridge portions of the truss rod arch structure were pre-assembled on land and "and dagger operation night-" in a May 22, 1905 by country and by a Frahms to the previously established abutment inserted. The completed pedestrian bridge was tolerated or approved shortly beforehand - there are two contradicting statements in the sources. It was initially called Märkischer Steg (sometimes Spreebrücke ) before the name Siemenssteig and from the 1930s Rohrdammsteg was given. Siemens then had the road inadequacies removed at its own expense.
The newly constructed pipe dam bridge was initially 64 m long, 4.5 m wide and secured on the sides with steel girder grids. In 1912/1913 it was widened to a total of 15 m on two lanes and two footpaths by an identical construction set up next to it - again with Siemens support. It was an iron arched truss bridge, free of electricity piers, of enormous height.
Towards the end of the Second World War , both parts of the Rohrdammbrücke were made impassable by blasting. The wooden makeshift bridge built afterwards proved to be unsafe for traffic and had to be demolished in the early 1950s. A modern prestressed concrete bridge was planned and the road layout changed. For structural reasons, two individual bridges were chosen that are offset lengthways by a few meters and span the Spree at an angle, making the entire structure 13 m longer than the previous building. The new pipe dam bridge made of prestressed reinforced concrete was constructed for the first time in Berlin using cantilever construction, in which concrete parts are made on land and, after hardening, connected to existing parts with tendons. The pillars are based on caissons . In 1954 the new Rohrdammbrücke was opened to traffic. Maintenance measures and safety work on the bridge were last carried out between 1982 and 1984.
As part of the German Unity Transport Project No. 17 , a new replacement for the bridge was planned in order, among other things, to enable the passage of two-layer container ships with a clearance of more than 5.25 m. The pipe dam bridge does not meet this requirement. Bridge building experts have ruled out an increase due to the difficult frame structure. Environmental associations and Bündnis 90 / Die Grünen criticize the expansion plans. The further implementation of the project within Berlin is currently suspended. On June 10, 2011, the planning approval procedure for this section was discontinued, so a replacement construction of the pipe dam bridge will not be pursued any further.
