Kattwyk Bridge

The Kattwyk Bridge is a lift bridge in the Port of Hamburg over the Süderelbe for rail and road traffic. The 290 meter long bridge connects Moorburg with the eastern Kattwyk peninsula, which belongs to the Elbe island Hohe Schaar or Wilhelmsburg . The Kattwyk Bridge was inaugurated on March 21, 1973 and, with its 70 meter high end portals, a lifting height of 46 meters, a passage height of 53 and a passage width of 96 meters, is the largest lifting bridge in Germany. At the time it was built, it was the world's largest lift bridge.

In addition to the Köhlbrand Bridge, a high bridge, located further north, it is the second bridge in Hamburg that even the largest ocean-going vessels can pass. For shipping to the four Harburg sea ​​ports with the Shell / Nynas refinery, it is usually opened every two hours during the day (during even hours). The interruption in vehicle traffic then generally lasts 15 to 20 minutes.

technology

The bridge consists of two trapezoidal trusses over the side openings and a parallel- belted truss above the main opening, which is suspended from 32  steel cables .

A special feature of the bridge are the railroad tracks that run in the middle of the tramway. Since rail and road traffic (still) share the Kattwyk Bridge, it must also be closed to road traffic for a freight train to pass through - usually eight to ten minutes. After the construction of the second lift bridge for the railroad (2017–2020) north of the existing one, this restriction will no longer apply.

Failures

In 1991 the Polish bulk carrier "Stanislaw Kulczynski" rammed the half-timbered superstructure of the bridge on the Wilhelmsburger Ufer. In heavy fog, despite two pilots on board, the ship did not pass under the middle section of the bridge, but hit an immobile 300-tonne side section of the bridge, which then broke off and landed in the water, the bridge keeper's house was also damaged and the bridge keepers became but fortunately only slightly injured. The repair cost several million DM and took nine months.

Due to the sharp increase in traffic and the associated high level of wear and tear, the bridge was taken out of service from April to October 2005 for basic repair work. The road surface, the rails and all 32 steel cables were renewed. In addition, the drive motors were completely overhauled and the steel structure was repaired and given new corrosion protection. In order not to impair shipping traffic despite the work, the 100-meter-long middle section of the bridge was wedged at the highest position. In March / April 2006 the bridge was again closed to traffic for rework.

Due to a bearing break on one of the four cable drums of the movable trough, the bridge was out of service from the end of January 2008 to December 15, 2008. After the bridge was blocked for about six weeks at a clearance height of 17 meters at medium high tide, it was raised to the maximum height in early March 2008. As a result of the blockade for large ocean-going ships that lasted several weeks, the transshipment companies located in the Harburg seaport basin suffered high financial losses. The long downtime was used to overhaul the entire drive mechanism of the bridge. In addition to replacing the defective bearing, the scope of the repair also included replacing all four custom-made cable drums. After the repair work was completed, the bridge was opened to road traffic again on December 15, 2008 by the Hamburg Senator for Economic Affairs, Axel Gedaschko and Jens Meier, Managing Director of the Hamburg Port Authority (HPA).

At the end of July 2011, the Kattwyk Bridge failed again during shutdown. After a fire in a switch cabinet, the bridge got stuck at a height of 8 meters and had to be raised to the maximum height again with an emergency drive. After the repair work, the bridge was put back into operation on September 10, 2011.

In autumn 2012, the railroad track was renewed and the bridge was closed to land traffic for three months.

The railway line over the Kattwyk Bridge connects the Hohe Schaar port station via Hausbruch with the Alte Süderelbe port station . This creates a possibility for trains from the western port to travel eastwards via the port railway and relieves the southern DB hubs Hausbruch and Harburg . To increase the line capacity and relieve the Kattwyk Bridge, a separate, very similar, double-track railway bridge north of the existing bridge is under construction. A connecting curve south of Moorburg to the Altenwerder container terminal will then further improve the connection.

In April 2014 the Supervisory Board of the Hamburg Port Authority (HPA) decided to build the railway bridge. According to the planning status in April 2014, construction should begin in summer 2014 and be completed in 2018. In May 2016, a schedule for the bridge construction (without preparatory work) from mid-2017 to spring 2020 was announced. It is called the New Kattwyk Railway Bridge .

On December 9, 2019, the 1,800-ton, almost 130-meter-long movable middle section of the new lift bridge was lifted into place with the help of two floating cranes . The first self-propelled hub took place at the end of April 2020. Further work will be completed by September 2020 so that traffic can begin in December 2020. The costs now amount to 250 million euros.

Based on experience with other railway bridges, a different construction is used for rail extension and rail joint.
