Swing bridge over the Geestemünder main canal
The swing bridge over the Geestemünde main canal in Bremerhaven - Geestemünde on Klußmannstrasse dates from 1861.
history
The Geestemünde seaport in the Hanoverian spot Geestemünde-Geestendorf was created and expanded from 1857 to compete with Bremerhaven, which was founded in 1827. The plans for the port facility from 1859 came from the hydraulic engineering director , building officer and admiralty councilor Heinrich Adolf Buchholz .
The main canal (today west of the canal and east of the marina) in Geestemünde was built at the same time as the transverse canal and the large basin of the commercial port until 1862. The two branch channels were supposed to establish the connection to the petroleum harbor and to the wood harbor . The main road coming from the south at that time led over today's Klußmannstraße (then Bahnhofsstraße) and Borriesstraße past the Geestemünder Markt (today Berliner Platz) to the Geeste with the first old Geestebrücke from 1857 to Bremerhaven. This road connection was cut by the new main canal.
Therefore the construction of a swing bridge was necessary as an important connection between the market and the former Geestemünder train station . A swing bridge was necessary to enable the crossing of ships and road traffic.
This bridge was also designed by the engineer Buchholz in the building era of historicism . The execution took place from 1860 to 1861 by the company Harkot from Haspe (today part of Hagen ), which was one of the leading bridge construction companies of the time.
With the large span across the main canal, the engineers opted for a two-wing bridge with the pivot point in the middle, similar to the first old Geeste bridge, for reasons of cost . The 45 meter long steel rivet construction rests on three pillars. The iron superstructure made of English puddle steel was rotated on a ring of 16 rollers on the central pillar with a diameter of seven meters. The drive mechanism of the movable upper part was operated by hand by three workers from the central pillar.
The trading port was completed in 1863, the petroleum port (now overbuilt) in 1875 and the wooden port in 1877 .
From 1881 to 1964 the Bremerhaven tram drove across the bridge as a single track ; the bus line 510 crossed the bridge until 2000. After that, the railway and most of the road traffic were led over Elbinger Platz, which was built over the partially filled-in ports.
In 1931 the bridge was rebuilt by the MAN Gustavsburg plant . She got an electric drive. In 1980 a major renovation was carried out by the Bremerhaven construction company Gustav W. Rogge. In 2003 the 140-tonne upper part was brought to the fishing port by a floating crane and restored there. The wooden walkways were replaced by steel and the gears and barrier systems were renewed.
The bridge is still operated today for the passage of pleasure boats.
In 2010, Bremerhaven's oldest movable bridge was placed under monument protection.
