The Hamm Railway Bridge (German: Hammer Eisenbahnbrücke) carries the Mönchengladbach–Düsseldorf railway over the Rhine between the Düsseldorf suburb of Hamm and the Neuss district of Rheinparkcenter in the German state of North Rhine-Westphalia. The original Hamm Railway Bridge was a double-track bridge built by the Bergisch-Märkische Railway Company from April 1868 as the first solid bridge across the Rhine in Düsseldorf and was opened on 24 July 1870. It was named the König-Wilhelm-Brücke ("King William Bridge") or König-Wilhelm-Eisenbahn-Rheinbrücke (“King William railway bridge across the Rhine”) after the Prussian King William I. It was built as a wrought iron arch supporting a three-span truss to plans of the engineer Pichier of the Harkort Company (Harkort’sche Fabrik) of Duisburg. The bridge towers on both sides reflected not only a need for architectural decoration, but also a desire to promote the military security of the bridge in the event of a war. For the same reason there was an outer fort at the side of the bridge, which was removed in 1885. Between July and September 1896, the approaches to the bridge were repaired and the track body was renewed under traffic. The whole construction was carried out in heavy traffic with all traffic handled on a single track.After 1896 the greatly increasing train traffic necessitated the building of additional infrastructure to complement the bridge. Between 1909 and 1911, a second, parallel, double-track bridge was built only 32 m upstream. It was built with the same distance between the piers, with a more modern and stronger superstructure as an iron truss arch. As with the older bridge there were bridge towers, but they were larger and stronger. Immediately after the commissioning of the new bridge, the modernisation of old bridge began, with the half-parabolic beams being replaced with new superstructure, which were identical to those of the second bridge. After its completion in November 1912, there were two quasi-identical bridges next to each other, with only the bridge towers differing significantly. During the Second World War, the U.S. Army conquered the neighbouring town of Neuss on 1 March 1945. To slow the advancing troops' crossing of the Rhine, the German Wehrmacht then blew up all the Rhine bridges in Düsseldorf, including the Hamm Railway Bridge, on 3 March 1945. Already in late 1945, temporary repairs began on the less damaged northern bridge, on which the two destroyed central arches were replaced by a temporary bridge made from standardised parts to the "Schaper-Krupp-Reichsbahn” design. Despite many difficulties, the bridge was already taken into operation on 31 July 1946. For the final reconstruction of the northern bridge, the least damaged arches of the identical southern bridge were substituted for the temporary spans; this exchange was completed in November 1947, removing the need for speed or weight restrictions. The ruins of the southern bridge were not rebuilt and the iron parts were used for scrap. The piers and bridge towers remain in a ruined condition. The construction of the east–west S-Bahn line S 8 in 1984 required the building of a new railway bridge to restore the Hamm Railway Bridge to four tracks again. The cost of this amounted to the equivalent of €61.4 million. In this case, the span for the shipping channel was greatly expanded. The new bridge was built to the south of the original bridge. The two-span river bridge has as its main span a 250 m long tied arch bridge attached to a through truss span built as a Warren truss with a span of 135 m. The construction is reminiscent of the historic structure. The bridge is designed so that two tracks are within the truss structure and a single track runs on both sides outside of the truss. The 9,000 tonne construction is fully welded. The bridge was built with heavy items of up to 100 tonnes built in an assembly area on the Düsseldorf bank and inserted in the final construction. The new bridge was opened in 1987 and had, until the opening of the Grümpentalbrücke (Grümpen Viaduct) on the Nuremberg–Erfurt high-speed railway with a 250-metre-long span, the longest railway bridge span in Germany. The old north bridge was then demolished and the bridge towers were left as a relic of the original bridge of 1870. The Bergische Lehnsritter e. V. club now has its headquarters in the towers.

Düsseldorf-Hafen
Düsseldorf-Hafen

Düsseldorf-Hafen is an urban borough of Düsseldorf, Germany, located on the river Rhine and the location of the city's docks. The borough covers 3.85 km2 and is predominantly commercial and industrial in nature, with a very small residential population. It had 212 residents in the year 2000, making it the Düsseldorf borough with the lowest population density. The docks prospered for decades but lost much of their trade when Mannesmann closed its nearby pipe factory. As a result the eastern part of the docks started to be redeveloped, attracting businesses in the service sector such as media, design and fashion companies. One of the first new residents to the so-called Media Harbour was Westdeutscher Rundfunk with its current affairs TV and radio studios. Düsseldorf local radio station Antenne Düsseldorf is also based in the harbour area. One of the largest cinemas of Düsseldorf is in the Hafen. The Landtag (State parliament) of North Rhine-Westphalia and the Rheinturm are situated right next to the harbour. Within the Hafen district is the Neuer Zollhof an ensemble of three warped-looking buildings by architect Frank Gehry and other postmodernist buildings. There are also many restaurants, bars, and a few clubs, which make the Hafen a prominent lifestyle district. The western part of the area still has actively used docks for barges that transport materials on the Rhine. There are plans for further redevelopment with the construction of high end apartment buildings. In 2003 the port company merged with the port of Neuss on the opposite bank of the Rhine to form Neuss-Düsseldorfer Häfen GmbH & Co. KG.
