The Upper Illerbrücken (also south bridges ) are two bridges in the urban area of Kempten im Allgäu that run side by side at an angle of 30 ° over the Iller . The structures were built by the Royal Bavarian State Railroad between 1904 and 1906. The old King Ludwig Bridge from 1851 is located directly next to the Upper Iller Bridge. The bridges are considered to be the largest stamped concrete bridges in the world.

history

Construction and use until 1969

1904 to 1906, the construction company Alfred Kunz from Kempten and Dykerhoff & Widmann (Nuremberg branch) built the arched bridges according to the plans of the construction council Beutel. The northern structure with four tracks served as a railway bridge for the main line to the old dead end station . The bridges were also used to change track and change direction . The bridge is 36 meters high.

The construction-like, southern bridge has served rail traffic with two tracks since its completion in 1906. Originally it led freight and long-distance traffic past the sack station to what was then the Kempten-Hegge through station . There was a train connection from the through station to the sack station in the center. The bridge has four arches and, like the sister bridge, is 36 meters high.

Both bridges are about 155 meters long and have openings of 21.6 - 21.6 - 63.8 and 21.6 meters respectively. The main opening is designed as a three-hinged arch .

Both bridges are under monument protection (files no. D-7-63-000-309).

Plan of the northern stamped concrete bridge

Change of use from 1969

After the construction of the new main station in 1969, the northern bridge was no longer needed for rail traffic and was converted for road traffic. Today it takes the four-lane Schumacherring ring road over the Iller.

Since 1969, the tracks on the southern bridge of the new through station have carried trains on the Illertalbahn ( Ulm - Kempten (Allgäu) ) in the direction of Memmingen and on the Bavarian Allgäubahn in the direction of Munich .

Others

The punk band Brutal Verschimmelt sang about the bridges in their song Illerbrücken (1982).

However, their spans were exceeded a few years later by the Walnut Lane Bridge (1908) | - 71 m - | in Philadelphia , Pennsylvania , USA , the Detroit Avenue Bridge (1910) | - 85.4 m - | over the Rocky River in Cuyahoga County , Ohio and the Monroe Street Bridge (1911) | - 85.6 m - | in Spokane , Washington . The Pont de la Liberation (1919) in Villeneuve-sur-Lot designed by Eugène Freyssinet had the largest span of all bridges made of stone or unreinforced concrete at 96 m.
