Emmerich Rhine Bridge

The Emmerich Rhine Bridge is 803 m, the longest suspension bridge in Germany and has with 500 the largest span m of a bridge in Germany. It was built by Hein, Lehmann and Co. ( Düsseldorf ), then part of the Stumm Group . The design of the bridge came from the civil engineer Hellmut Homberg , the architecture professor Heinrich Bartmann participated in the design.

The structure spans the Rhine between Kleve and Emmerich at a height of around 30 m at kilometer 853.2. It is the northernmost German Rhine bridge. The overpass has two lanes, two lanes and two sidewalks and is part of the federal highway 220 . The Prime Minister of North Rhine-Westphalia , Franz Meyers , laid the foundation stone on May 2, 1962 . The Emmerich Rhine Bridge was opened on September 3, 1965.

As part of the building tender , Fritz Leonhardt , with advice from Gerd Lohmer , designed a monocable suspension bridge with a streamlined deck. Although the new construction was 15% cheaper than the conventional design, it was not implemented because there was no experience with it.

In January 2019, the renovation of the Rhine bridge began, which will take four years and cost 28 million euros.

Suspension bridge

The real suspension bridge with the two anchoring blocks has a length of 893 m. It has spans of 151.5 m in the peripheral fields and 500.0 m in the main field. The structure has two 76.7 m high steel pylons . The posts of the pylons are inclined at the top by 5.8 m towards the bridge axis and connected by a 5.5 m high crossbar. The trapezoidal stem cross-section has the external dimensions of 4.0 m in the longitudinal direction of the bridge and 3.25 m in the transverse direction on the river piers and 2.5 m and 3.25 m at the pylon head.

Two suspension cables, consisting of 61 individual ropes, with an outer diameter of 45 cm and spaced 16.8 m apart, run over the pylons. The cable slack between the pylon and the middle of the bridge is 55.56 m. The suspension cables are attached to the suspension cables at a distance of 15.15 m. These support the 4.5 m high steel bridge superstructure. The superstructure consists of two stiffening girders in the longitudinal direction, which are designed as a 70 cm wide postless strut framework. Between the upper chords of the truss girders, the cross girders, which support the bridge panel, span at a distance of 2.53 m. This is a 22.5 m wide orthotropic slab that protrudes 2.5 m over the main beams on both sides. In the central opening, the bridge also has a wind brace on the underside to ensure sufficient stability .

Foreland bridge

There is a 37.5 m long anchoring pier between the river and foreland bridge. The foreland bridge on the left bank of the Rhine is a five-span 341 m long prestressed concrete bridge . Starting at the west abutment, the spans increase from 59.5 m to 64.5 m, 68.5 m and 72.5 m to 76.0 m in front of the anchoring pillar of the suspension bridge. The construction height of the girder bridge increases accordingly from 3.04 m to 4.19 m. In the transverse direction, the structure has a two-web T-beam cross- section with a deck that protrudes 5.25 m on both sides and is 21.6 m wide.
