Salt Gate Bridge
The Salztorbrücke crosses the Danube Canal in Vienna and connects the 1st and 2nd district, the inner city and Leopoldstadt .
location
In addition to the name Salztorbrücke, the Salztorgasse, which leads from the 1st district to the bridge, and the street called Salzgries in the 1st district also indicate the salt trade once operated in the area . In addition, from 1546 to 1564 the Imperial Arsenal was located in this area , where warships were built for the Danube .
In his planning for the Danube Canal in the 19th century , Otto Wagner envisaged the location for the central fish market in Vienna above the Salztorbrücke on the right bank - on Franz-Josefs-Kai . The quay wall, which is otherwise always steep, is designed as a step quay in this section. The fish market existed here from 1904 until it closed in 1972.
Above the Salztorbrücke, the “National Park Boat” departs from the left bank of the Danube Canal (2nd district) to the Donau-Auen National Park in Lobau .
1827–1884: Karlskettensteg
The Karlskettensteg (also Karls-Steg) was built as a chain suspension bridge in 1827/1828 and named after Archduke Karl , the winner of the battle of Aspern against Napoléon Bonaparte . In 1870 the footbridge had to be torn down because the bridge's low weight kept vibrating. Then a wooden truss was erected to replace it, which lasted 14 years.
1884–1945: Stephaniebrücke, Salztorbrücke
Since the Karlskettensteg was only a narrow footbridge, a wider bridge was built from 1884 to 1886, which was named Stephanie Bridge after Crown Princess Stephanie , the wife of Crown Prince Rudolf . The architect was Otto Hieser and the chief engineer was Adolf Schmid von Schmidsfelden . From here, from 1886 to 1901, a line of the Dampftramway company (formerly Krauss & Comp.) Ran on the Leopoldstädter Ufer , past the Augarten Bridge, towards Floridsdorf , Stammersdorf and Groß-Enzersdorf . In 1901 the departure point was relocated to the Augarten Bridge.
After the end of the monarchy, the Stephaniebrücke was renamed Salztorbrücke by the social democratic city administration in 1919, after the so-called Salt Gate of the Vienna city wall . The bridge was adjacent to the Hotel Metropol in the 1st district , which served as the Vienna Gestapo headquarters from 1938–1945 .
In April 1945 the bridge was blown up by the defenders against the Red Army in the course of the Battle of Vienna .
1960 – today
As the last of the Danube Canal bridges destroyed in the war, the Salztorbrücke was rebuilt in 1960/1961 as a prestressed concrete bridge based on a design by Herbert Wycital. Clearance regulations and a flat road level led to the transom being particularly slim. In addition to the very low construction height in the middle of the bridge of approx. 1.3 m, the height above the posts, which is 2 m compared to other concrete bridges, should be emphasized.
The bridge achieved a particularly high pre-tensioning force and higher compressive stress on the frame ledger. In order to keep the deflection in frame, the stems were replaced by a pendulum wall and a prestressed tension wall only 20 cm thick, which were closed with concrete aprons on the sides that are not connected to the tension and pendulum wall. Presses were chosen to absorb the horizontal thrust, which connect the foundation and the quay wall with a foundation support. The tendons were tensioned according to the Baur-Leonhardt system. The anchoring of the spans was done by setting the wire package in concrete.
On November 25, 1961, the newly built Salztorbrücke was opened by Vice Mayor Felix Slavik . A skyscraper belonging to the Raiffeisen-Landesbank Niederösterreich-Wien is located next to it in the 2nd district, at the so-called Friedrich-Wilhelm-Raiffeisen-Platz on Hollandstrasse.
