Ivančice Viaduct (1978)

The Ivančice Viaduct ( Eibenschützer Viadukt , formerly Iglawa Viaduct , Czech Ivančický viaduct ) is a railway bridge on the railway line (Vienna–) Hrušovany nad Jevišovkou – Brno in the Czech Republic . It leads the train between the stations Moravský Krumlov ( Mährisch Kromau ) and Moravské Bránice ( Mährisch Branitz ) about three kilometers southeast of the town of Ivančice ( Eibenschütz ) over the Jihlava valley . As a scaffold pier viaductWhen it was commissioned in 1870, it was the largest such bridge in Europe and the first large bridge in Austria-Hungary made entirely of iron .

The old bridge was replaced in 1978 by a modern, parallel building. A preserved torso of the old bridge stands as a cultural monument under monument protection .

Lattice girder bridge (1870)

The viaduct was built between 1868 and 1870 by the Austro-Hungarian State Railway Company as part of the route from Vienna to Brno (Brno) , on which the Stadlauer Ostbahnbrücke in Vienna was built immediately afterwards . It was planned by Karl von Ruppert and built by the French company Ètablissement Cail , which at the same time was involved in the construction of the similarly constructed Viaduc de Busseau and Viaduc de la Bouble in France. It was the first bridge in Austria-Hungary made entirely of wrought iron .

The single-track, 373.5 m long bridge with 6  fields of 60 m each crossed the river at a height of 42.7 m. The 5.6 m high, continuous track support of wrought iron lattice girders with overhead roadway has been mounted on the track and then in sections from both sides to the five pillars inserted .

The pillars consisted of four cast iron pipes of the same length, mounted on top of each other in levels, with an outside diameter of 50 cm and a wall thickness of 4.5 cm, which were filled with concrete after installation. The pipes were stiffened with wrought iron struts and mounted on masonry plinths that reached up to the same height (with the exception of the slightly higher first pillar on the western slope).

1238 tons of wrought iron and 206 tons of cast iron were used in the construction. After the successful stress test on August 20, 1870, the ceremonial opening took place on September 15, 1870, which was celebrated with a week-long party.

The cast-iron load-bearing elements in the pillars had to be replaced by sectional steel in 1892. The exchange was carried out in 6 months.

Box girder bridge (1978)

At the beginning of the 1970s, the old bridge had reached the end of its service life after over a hundred years of use. In 1972, 15 m downstream from the old bridge, construction began on a completely new bridge, planned by Železniční stavitelství Brno ( Brno Railway Construction Office ), with a continuous box girder , which is a total of 387 m long and whose tracks are 44.5 m above the river bed. The steel superstructure of the bridge was manufactured and installed by Vitkovické ocelárny ( Witkowitz Iron Works ). This bridge was put into operation on November 9, 1978.

The old, listed bridge was subsequently demolished except for a short section with a pillar on the northern abutment.
