The Viadukt Oschetztal is a railway bridge on the Werdau – Mehltheuer railway line , which is considered to be the first pendulum pillar bridge in Germany. Due to dilapidation, the bridge was taken out of service in 1982 and replaced by a parallel embankment. It has been a listed building since 1977.
The viaduct is 185 meters long, 28 meters high and spans the Oschützal valley and today's federal road 92/175 in the urban area of the city of Weida in Thuringia . It was built in 1884 according to plans by Claus Koepcke and the engineer Hans Manfred Krüger .
The steel of the approximately 380 t heavy structure came from the Queen Marienhütte in Cainsdorf .
history
The single-track railway line Mehltheuer – Weida was put into operation in 1883, but ended at the former Weida-Altstadt terminus. The Prussian Weida train station on the Leipzig – Probstzella line was at the other end of the city. If you wanted to travel further in the direction of Gera, Werdau, Leipzig or Saalfeld, you had to cover an arduous walk through all of Weida. Since the Royal Saxon State Railways and the Prussian State Railways could not agree on a common route and the Schüttdamm at the confluence with the Prussian Weida train station often slipped, it was decided to bridge the Oschützal valley.
The building was completed and handed over on October 1, 1884. As early as 1915, the viaduct had to be reinforced due to the increasing volume of traffic. This was done by installing a central beam and additional bracing of the pendulum supports.
In 1977 the viaduct was listed as a historical monument. After almost 100 years of operation, the building had reached the limit of its useful life and a speed limit had to be set up. The route was given a new route on an embankment parallel to the Gera – Saalfeld route. On September 22, 1982, the last train ran over the Oschützal Viaduct as scheduled. Since then, the building has not been used.
In 1984 an investigation into the future of the viaduct was carried out. The demolition of the monument was prevented by several petitions from Weida citizens. The condition of the viaduct is very bad and repeatedly gives rise to discussions about the future of the technical monument. There are 2.5 million euros in renovation costs or 500,000 euros in demolition costs. As a unique technical monument in Germany, the preservation of the building is worth striving for. For some time now, the association "Oschetztal-Viadukt eV" has been fighting for the preservation of the technical monument. With creative campaigns, fundraising, lectures and guided tours, attention is drawn to the viaduct and its condition. The aim is to preserve the unique traffic engineering monument.
description
A lattice girder was chosen as the cheapest way of bridging the Oschützal, the support of which was carried out according to the system of oscillating pillars (pendulum supports). The viaduct consists of two parts, the 101 meter long main part and the 54 meter long smaller part. At the two ends of the viaduct, two stone arches have been built, resulting in a total length of 185 meters. In this design, the parallel-chorded iron shed supports were partly supported on pendulum supports. The pendulum supports are articulated so that they can follow the change in length of the girders caused by temperature fluctuations. The weight of the iron structures is around 380 tons.
