The city ​​viaduct and the Ruhr bridge Mülheim as well as the foreland bridge west of the Ruhr are a continuous structure that was built in 1864/65 according to plans by senior building officer Emil Hermann Hartwich .

history

The system was built by the Rheinische Eisenbahn-Gesellschaft and was part of the Osterath – Dortmund Süd railway line in Mülheim an der Ruhr . The line branched off from the left Lower Rhine line at Osterath and led from 1866 via Mülheim to Essen , later also to the Holland colliery in Wattenscheid (1867) and as far as Dortmund (1874).

Two iron arches spanned the Ruhr, the third over the still existing Ruhrstrasse. They were manufactured by Kölnische Maschinenbau AG in Bayenthal according to Hartwich's specifications . The city viaduct connects to the left and right of the river, and the structure consists of 39 arches . A million bricks were built and the mortar required for this was produced in specially built mills on both sides of the Ruhr. The three iron arches together weighed 500 tons, and 6,800 rivets were driven in.

In 1926, the three iron arches of the bridge, which were located below the carriageway, were replaced by the current structure, which consists of three pairs of crescent or pressed parabolic truss arched girders. They start below the level of the roadway, but cut through it and form flat, elongated arc segments above. As part of the new building, a pedestrian walkway was built on the south side of the bridge at the expense of the city of Mülheim, which was accessible via stair towers on both sides of the Ruhr. The designs of the new arches were from Reichsbahndirektion food , the execution took over the Düsseldorf steel -Unternehmen Hein, Lehmann & Co .

At the end of World War II , the middle arch was blown up by the military. The bridge was soon made usable again as a single track by means of an auxiliary construction. In 1950/50 the middle section was renewed by the Dortmund company August Klönne based on the old model, but without a footbridge; this was only supplemented in 1963 in the form of a steel box girder beam. In 1974 the stair towers were demolished except for the lower part of the city-side staircase; An open staircase was created on the west side.

The line was closed in 2002, and some of the tracks have already been dismantled.

Market halls , shops and storage rooms were housed in the viaduct arches in the city area ; today they are open.

On the right side of the river are the Rathausmarkt and Rathausmarkt, on the left the Mülheimer Gartenschau can be reached.

In 2016, the renovation of the bridge to the Ruhr cycle route or the so-called "Stadtviadukt-Boulevard" began. The work was completed in spring 2019 and the new section up to the Ruhr West University of Applied Sciences officially opened on May 15, 2019.
