The oldest of the bridges in Munderkingen in the Alb-Danube district in Baden-Württemberg is usually referred to as the Munderkinger Danube Bridge . It connects the town center, located in a loop of the Danube , with the district north of the river, especially with the train station on the Ulm – Sigmaringen railway line . It leads the state road 273 over the Danube and connects it with the state road 257 running north of the river.

The Munderking Danube Bridge, built in 1893 from rammed concrete , replaced a previous wooden structure. She was the first three articulated concrete - arch bridge , followed by a variety of the same system built bridges. After it was blown up shortly before the end of the Second World War , it was replaced by a reinforced concrete bridge in 1948 .

The stamped concrete bridge from 1893

The old wooden bridge over the Danube was so damaged in 1892 that it urgently had to be replaced. The new bridge could be built next to the old bridge, which improved the entrance to the city after a building was demolished and saved the construction of an emergency bridge.

The bridge, designed by Karl von Leibbrand as President of the Ministry of Road and Hydraulic Engineering of the Kingdom of Württemberg , was built between April 11 and November 15, 1893 by Max Buck, Ehingen , and opened to traffic on the following day .

The two-lane road bridge, including its abutments, was around 70 m long. It crossed the river at a slightly sloping angle and with a 3% gradient to the north. The bridge was 8 m wide within the parapets, divided into a 5.40 m wide carriageway and the two 1.30 m wide walkways. There were concrete parapets on the abutments, which were replaced by wrought iron railings above the river opening. The apex of the arch was marked on both sides by clearly protruding keystones on which a statue of St. Nepomuk stood and on the other side a large wrought-iron candelabra .

In each abutment there was a 2.50 m wide, arched passage for the bank paths.

Your big arc over the Danube was without reinforcement in concrete printing run. It had a span of 50 m and was the largest concrete arch in the world at the time. At the same time, it was the first three-hinged concrete arch with separately calculated and constructed joints. It was 7.56 m wide. The arch thickness was 1.0 m at the top, 1.4 m at the arch quarter and 1.1 m at the fighters . As the bridge axis was not at right angles to the direction of the river, twelve individual joints were arranged on each side, slightly offset.

The right abutment was founded directly on the adjacent rock, while the left abutment stands on a 14.2 m wide and 9.5 m long foundation, for which a pile foundation with 145 piles was created, which are inclined 15 ° to the vertical.

The bridge, in which the pipes for the water and electricity supply for the town ran, served its purpose for over 50 years without any complaints. However, shortly before the end of World War II , on April 22, 1945, it was blown up by the Wehrmacht, before US troops occupied the place the next day.

The new Danube bridge was designed by Wayss & Freytag and built in 1947/48. Its external shape is similar to the old bridge, but it is a little wider. Your deck slab of reinforced concrete is of two strong haunched prestressed concrete - box girders borne m with spans of 43, which replicate the arc shape of the original bridge. It also has arched passages for the bank paths on both banks. A statue of St. Nepomuk has now been placed on a pedestal on the city-side abutment. In the passage for the riverside path below the statue of St. Nepomuk there are various high water marks , with the mark of the high water from March 16, 1760 at the top halfway up the passage.
