The Michaelbrücke is a fixed Spree crossing that replaces the first bridge from the end of the 19th century. It is located in the Berlin-Friedrichshain district and connects it with the Mitte district .
history
In 1876, work began on a bridge structure on the 62 meter wide river bed to relieve the increasing traffic volume. It was the first urban bridge that the Berlin magistrate had taken over as magistrate property on the basis of an agreement with the Prussian state. The construction plans, which still came from the state, meant a standardized bridge construction program, which both reduced costs and made it possible to build further bridges in a slightly modified form.
A three-span wrought-iron 70 m long arched truss bridge with spans 19.69 m, 30.80 m and 19.13 m was built. The stone pillars with red clinker bricks were decorated with depictions of Berolina and Borussia , which symbolized the sharing of construction costs between the city of Berlin (= Berolina) and the Prussian state (= Borussia). The relief of a bear as the heraldic animal of Berlin , on the other hand, marked the current ownership situation. Since the construction height of the bridge apex was just 65 centimeters, the bridge builders laid the supply lines below the sidewalks.
During the Second World War towards the end of the Battle of Berlin , Wehrmacht specialists blew up the eastern arch of the bridge in order to prevent the advance of the Red Army . In the post-war period, a wooden auxiliary construction was used for pedestrians. It was not until the 1970s that the eastern bridge field could also be restored for car traffic. The lines, now supplemented by district heating lines from the thermal power station, were now laid in pipes two meters above the sidewalk. Due to its proximity to the border to West Berlin , the GDR government left the bridge in its condition, which was visibly deteriorating.
The German reunification allowed since 1991 to build a completely new bridge. The architects Joachim Dörr, Axel Ludolf and Josef Wimmer (Dörr Ludolf Wimmer) designed a new 72-meter-long three-span steel bridge to replace the dilapidated bridge at almost the same location. The design was based on the filigree construction of the previous bridge, but cannot be compared with it in terms of design. The northern location of the earlier pillars was retained because the road leading to it leads through an arch of the railway viaduct. The engineering office Gregull + Spang carried out the structural planning . The construction work for the new structure was carried out by Gruwa GmbH , Krupp Stahlbau and Teerbau GmbH . It was given a southern abutment seven meters further inland and runs slightly diagonally across the river. The Michaelbrücke is a traffic alternative between Jannowitzbrücke and Schillingbrücke . The new tour created space for a waterfront promenade, which has not yet been created (as of the end of 2017).
Constructive
The construction height was restricted by the routing of the road below the S-Bahn viaduct and by shipping requirements. The bridge superstructure consists of three horizontal main girders, each with a lateral cantilever arm as an extension of every second cross girder. There are two lanes on each side and a sidewalk on each side. All 70 pipeline routes could be laid under the longitudinal girders, which were given a clear look by covering them with grating plates. The new bay widths are 19.5 m on the sides and 31.0 m in the middle of the bridge. The pillars were designed as elliptical panes based on boat construction and, together with the bridge railings, were modeled on a ship's railing. The sculptor August Jäkel designed brass reliefs for the illuminated end fields of the bridge, which show the old bridge, a longitudinal section through the new structure and the coats of arms of the two connected districts.
Neighboring and medial
On the southern bank next to the bridge are the buildings of the central heating power station belonging to the Vattenfall Group and the site of the former open-air club Lichtpark, which was closed in 2015. On Holzmarktstrasse, at the northern end of the bridge and directly on the railway line, there is still a piece of brickwork from the original bridge. Here the three-part Trias building dominates the beginning of the bridge on the west side . Another office and hotel complex was to be built on a 12,000 m² plot of land owned by the Berlin city cleaning service on the same corner , on which used furniture was sold in a barracks until 2001. It is now planned to build the "Eckwerk" residential project on the property.
The Michaelbrücke has already served as a backdrop for commercials and film recordings.
