The Oberhafenbrücke is a combined rail and road bridge in Hamburg . The lower level is reserved for road traffic; on the upper level, all of the long-distance trains crossing the Elbe between Hamburg Central Station and Hamburg-Harburg Station are carried on four tracks .
The bridge was built as a truss bridge from May 1902 and completed in May 1904. It crosses the Oberhafen , a connection between the Norderelbe shortly after Rothenburgsort and the Zollkanal . In 2007 it was replaced by a new design.
history
The reorganization of rail traffic in Hamburg, including the expansion of the connecting line and the construction of the main train station, which was completed in 1906, made the unfavorably located Hanover train station superfluous for passenger traffic, which then served as a freight station. To connect the network to the Elbe bridges, the Oberhafen, which runs parallel to the Elbe, had to be crossed. The route was carried out on the pillar railway built at the same time .
In 1902 the Prussian railway administration commissioned a working group with planning and bridge construction. At the same time, it was intended to be used as a road bridge with a clearance of 4.40 m. A footbridge was built on both sides of the half-timbered construction for pedestrians.
The bridge construction was executed as a riveted truss, the two main girders together weighed 1,300 t.
Ship traffic should still be possible, which made a construction as a swing bridge necessary. Elaborate construction of the pillar to accommodate the rotating mechanism for the bridge, which was operated using compressed air generated by a gasoline engine. The entire turning process could be completed in four and a half minutes. In the course of the electrification of the route, catenary masts were attached to the bridge structure in 1964.
The foundation of the bridge was reinforced in the mid-1980s. All pillars were framed with new sheet pile walls. In the spaces between the old pillars and the new sheet pile walls, double-T girders were driven into the load-bearing soil layers. Because railway operations were not allowed to be interrupted on the four tracks, the height of the work area was severely limited. The girders could therefore only be rammed into the subsoil in sections and had to be welded together from several short parts as the ramming progressed. The space between the new sheet pile walls and the old pillars was filled with concrete. The pier heads were completely renewed and received new supports for the half-timbered superstructures . In the course of this work, the parts of the no longer functional turning mechanism were removed.
replacement
The high load from the increasing traffic frequency and also from the higher weight of the trains put a considerable strain on the old construction and made it necessary to replace the construction.
The steel construction work for the 3,529 t heavy construction was carried out by the company Eiffel Germany Steel Technology .
The 49 new individual parts were assembled on the neighboring site of the former Hanover train station. The completely assembled bridge was brought to its destination in one piece via an auxiliary structure. The streets Stadtdeich and Stockmeyerstraße are crossed with two double fields.
In the last week of December 2007, the old bridge was dismantled into several parts and transported away with pontoons that were maneuvered under the components at low tide.
The pillar on which the rotating mechanism was located is larger than the rest of the pillars. It remained unchanged when the bridge was renewed.
various
- On the occasion of an exhibition by the Swiss artist Rémy Zaugg in the Deichtorhallen in 1992, the words “Canals, railway bridge, warehouses, ship, clouds, sky, wind, harbor cranes” were placed in large white letters. After the bridge was renewed, the words were put back in place. The writing can be read from the west.
- At the city dike there is a sliding gate for flood protection, which can lock the flood protection system against the bridge deck.
- The Oberhafenkantine is located on Stockmeyerstrasse partly under the bridge.
- The Oberhafen stop south of the bridge on the pillar railway was abandoned in 1944. Today there is a bus stop named after the bridge in the immediate vicinity of the building, but it is only served from time to time.
- The memorial plaque for the flood of the Elbe of 1771 is now in the Banksstrasse / corner of Oberhafenstrasse at the northern abutment of the Oberhafenbrücke ( → Lage ) and has been a listed building since 1961.
- The Elberadweg leads past the Oberhafenbrücke.
- The Oberhafenbrücke is often used as a filming location for various television and video productions. For example, she can be seen several times in episodes of the Hamburg cult series Großstadtrevier (episode 334 Pretty Woman ) and in the children's crime series Die Pfefferkörner (episode 123 Tests of Courage , episode 126 Danger from the Right ). In addition, you can sometimes find the building in music videos. The band Beginner , Johannes Oerding and Lina Larissa Strahl used the bridge as a backdrop for their videos.
