Bridge landscape Ruhraue

from Wikipedia, the free encyclopedia
Location of the bridges

The Ruhraue bridge landscape is an ensemble of bridges over the Ruhr on the city limits of Duisburg and Mülheim an der Ruhr, so called by Route der Industriekultur .

The bridges at the transition from the slate mountains on the right bank of the Rhine to the Rhine plain in the area of ​​the Kaiserberg in Duisburg include railway bridges dating back 140 years and road bridges , including several motorway bridges.

Location and function

The bridge landscape can be roughly divided into two sections, an eastern part along the Ruhr Canal between Ruhrschleuse Raffelberg and the mouth of the old Ruhr arm and a western part downstream to the mouth of the Rhine-Herne Canal .

Eastern part

In the eastern section, the bridges run roughly in a west-east direction over the Ruhr canalized in this section, the Ruhr shipping canal completed in 1927 :

Motorway bridge: ( 51 ° 26 ′ 32 ″  N , 6 ° 49 ′ 8 ″  E )

The first crossing of the Ruhr in the direction of the river is the motorway bridge of the federal motorway 40 . It has been expanded to six lanes, although the motorway continues only four lanes on both sides of the bridge, but two acceleration and deceleration lanes each of the Kaiserberg motorway junction are connected to the south bank .

Railway bridges over the Ruhr Canal as seen from Schwiesenkamp

Railway bridges Kaiserberg:

A total of seven (previously eight) lattice girder bridges cross the Ruhr a little less than a kilometer downstream. Two of the most important railway lines in the Ruhr area, the railway line from Duisburg to Oberhausen of the Cologne-Mindener Eisenbahn-Gesellschaft (CME) and the railway line from Duisburg to Mülheim (Ruhr) of the Bergisch-Märkische Eisenbahn-Gesellschaft (BME) run over it.

The northernmost bridge (7) goes back to the construction of the main line of the CME in 1847 and has been double-tracked since 1851. The middle bridge (4) originates from the construction of the Ruhr area line of the BME in 1862 and was widened and renovated in 1974 as part of the construction of the S-Bahn. The southernmost bridge structure (1), consisting of two partial bridges, originally dates from 1911. In 2019, a new structure replaced both bridges.

There are plans to build three more bridges from the 1920s.

Kolkerhof Bridge

Kolkerhof Bridge: ( 51 ° 26 ′ 50.5 ″  N , 6 ° 48 ′ 22 ″  E )

The last in this ensemble a road bridge connects the small hamlet Werthacker combines with the field of Kolksmannshofes. The street that leads over this bridge is called "Schwiesenkamp", which is why the bridge is also called the Schwiesenkampbrücke by the locals . Except for local traffic, you only come across pedestrians and cyclists here.

Western part

In the western section, the bridges are all oriented in a north-south direction. While Landstrasse 140 (called "Ruhrdeich") runs along the southern bank of the Ruhr, the floodplains of the Ruhraue are located at the northern bridgeheads :

Motorway bridge: ( 51 ° 26 ′ 56 ″  N , 6 ° 47 ′ 55 ″  E )

After the confluence of the old Ruhr arm, the first thing to do is to cross the Ruhr on federal motorway 3 , which consists of a bridge in each direction of travel with three lanes and a hard shoulder.

The first motorway bridge at this point was planned as part of the Reichsautobahn program and opened on December 12, 1936, back then as a simple, four-lane road without hard shoulder and with only minimal structural separation of the directional lanes.

Railway bridge: ( 51 ° 26 ′ 56 ″  N , 6 ° 47 ′ 52 ″  E )

Immediately to the west, downstream, is a four-track railway bridge with three steel lattice arches with massive drainage bridges .

The first bridge at this point was built in 1879 by the Rheinische Eisenbahn-Gesellschaft (RhE) as part of their Duisburg – Quakenbrück line. The Prussian State Railways (PSE) expanded the line by a second track in 1890/1. In 1911, PSE opened their new freight line from Duisburg-Wedau or Duisburg Hochfeld to Oberhausen West , adding the third and fourth track.

During the Second World War , the bridge was destroyed and traffic was diverted via an alternative route that led through the Ruhraue in a wide arc past Kolkmannshof to the Kaiserberg junction. This route, of which only individual sections of the former railway embankments in the Ruhraue are preserved today, was abandoned in 1948 after the direct bridge connection had been restored. Today all four tracks are used for freight traffic.

new Aaker ferry bridge, opened to traffic in 1997

Aaker ferry bridge: ( 51 ° 26 ′ 59 ″  N , 6 ° 47 ′ 31 ″  E )

In the far west of the Ruhraue, the Aaker ferry bridge connects the Duisburg districts Duissern and Meiderich as a four-lane road bridge .
