Tulln Danube Bridge
The Tullner Danube Bridge in Lower Austria crosses the Danube at river kilometer 1963.20 and consists of a railway and a road bridge.
history
The Kaiser-Franz Josefs-Bahn , opened in 1870, was initially led over the Danube on a temporary wooden bridge in Tulln . It was not until 1872 that the Compagnie de Fives-Lille was commissioned to build an iron bridge for rail and road traffic.
Initially, however, only the iron structure for a railroad track was built. The road bridge was later built at the expense of the Province of Lower Austria. Material damage made it necessary to reinforce the sleeper girders of the railway bridge in 1894. After the second track had also been laid, these sleeper girders were also reinforced in 1899.
Due to the structural condition of the bridge, it was decided in 1902 to rebuild the iron bridge structure. The bridge piers were preserved.
In order to be able to maintain rail traffic during the new construction of the bridge, the truss construction of the new railroad bridge was built in place of the previous road bridge and the rail connections were adapted to the new conditions. The former railway bridge was then converted into a road bridge. This change of side also made it necessary to shift the supporting structure of the previous railway bridge and the current road bridge by 40 centimeters downstream.
In 1904 the new railway bridge was built and rail traffic began in March 1905. In May 1905, the converted road bridge could also be opened to traffic.
At the end of the Second World War, the Tulln Danube Bridge was blown up. Four of the five structures were destroyed in the process, so that one end of them rested on a bridge pillar and the other on the bottom of the Danube. Only one of the bridge structures was only slightly damaged. The abutment on the left bank of the Danube was also destroyed.
The general lack of material prevented the construction of a completely new bridge and forced the designers to carry out the bridge renovation using the remaining bridge parts. Due to the time pressure, it was decided not to dismantle the structural parts, to replace parts that were no longer usable with new ones and to rebuild the Tulln Danube Bridge from these components.
On January 20, 1947, work to raise the first bridge span began. For this purpose, assembly scaffolding was erected above the bridge structure. First one half of the supporting structure was lifted and then fixed. Damaged structural parts were removed and replaced with newly made parts. Since the extent of the respective destruction could not be estimated beforehand, the required parts could only be adapted to the needs on site. On June 10, 1948, work to restore four bridge structures was completed.
At the same time as this work, the fifth bridge structure was first dismantled and then completely rebuilt. In contrast to the restored bridge structures, this one was built with a wider meshed buttress framework.
The completely destroyed masonry of the so-called Absdorf abutment on the left bank of the Danube had to be removed down to the caisson surface and was replaced by a concrete wall without granite stone cladding .
The work on the restoration of the Tulln Danube bridge was carried out by the
- Waagner-Biro AG with its workshop in Stadlau , the
- Construction company Pröll (Absdorfer abutment),
- Zimmermeister Frischauf in Tulln (scaffolding work) and the
- Gesellschaft für Bauarbeiten Buchecker & Co. (painting work).
The traffic was opened in 1948. In 1983 the bridge was lifted as a result of the construction of the Greifenstein power plant .
From July 2008 the pillars of the Tulln Danube bridge were renovated. From March 22nd, 2009 the railway bridge was closed and completely renewed, which also partially affected the road traffic that was diverted over the Rosenbrücke . The Tulln Danube Bridge was opened for road traffic on October 26th, and passenger traffic on the new structure took place on October 27th, 2009. The structures of the railway bridge were partly dismantled from the banks and partly floated out in May with pontoon ships and then on North bank, where the new bridge parts were also assembled, dismantled.
Two new bridge structures, each 182 meters long, were installed on June 17 and July 10, 2009, also by floating in using pontoons. The two peripheral fields were built from the bank.
In addition to the complete renovation of the structure for the railway, a new bridge was built in the urban area of Tulln and three more were rebuilt.
description
The 440-meter-long Tulln Danube Bridge was built from a double-track railway structure and a downstream structure for a two-lane road and a sidewalk. Each of the structures was constructed from truss girders . They use the bridge piers and the abutments together .
Because of its proximity to the city center of Tulln, the new bridge structure was equipped with noise barriers and a solid roadway. The tracks were poured into cork-bitumen granules.
The construction of the bridge structure is part of the reactivation of the so-called Tullner Westschleife .
