Weinzöttl Bridge
The Weinzöttlbrücke (also spelled Weinzödlbrücke ) is a listed road and railway bridge over the Mur in Graz . On the northern edge of the city near St. Veit - Weinzödl ( St. Gotthard locality ) the Grazer Straße (B67) and the towing railway from Gösting to Andritz over the river.
history
The permission to build the first wooden bridge over the Mur was given to the Eggenbergers on February 4, 1673. The roadway of this bridge was removed after the opening of the Weinzöttlbrücke, but the pillars were retained and were later used to build a pedestrian walkway. It was opened on October 7, 1923 and finally torn down in 1953 and 1954.
Already before the First World War, a community of interests of local industrialists was formed, which called for the construction of a railway connection from Gösting via Andritz to Sankt Radegund with connections to the Zankl paint factory in Gösting, the Kranz paper factory in Unter-Andritz and the Münz gravel works.
The planning of a spacious bridge over the Mur, which began before the outbreak of war, was reduced in 1916 due to the war. In 1917 construction work began on the railway line, which included a total of 10 bridges to bridge roads and waterways.
The Weinzöttl Bridge as the main structure was built as a joint road and rail bridge. It has three openings of 2 × 33 meters and an additional flood opening of 28 meters clear width. The bridge length between the land abutments is 120 meters.
The bridge was calculated as a railway bridge with load norm II and as a road bridge 1st class, whereby a regulation from July 15, 1911 regarding the pressing of concrete was valid for the stamped concrete and reinforced concrete .
During the construction work started in 1918 and carried out by the construction company Mayreder, Kraus & Co., a temporary wooden bridge was erected along the downstream half of the Weinzöttl Bridge. The falsework for this bridge section was later erected on their yokes. This temporary bridge was used for the first time on a trial basis at the end of June 1918, and regular rail traffic to Andritz began on August 1, 1918.
In July 1920, rail traffic on the concrete bridge, which had been designed for a standard-gauge industrial track, was resumed and the wooden bridge previously used was removed. By April 1921, work on the downstream half of the bridge had also been completed. The 9-meter-wide bridge deck, made of reinforced concrete, was paved with a small stone paving made of granite in sand, while the two 1.5-meter-wide sidewalks were paved with asphalt.
The endurance test was carried out in August 1922. On December 3, 1922, the bridge was opened to traffic in the presence of Federal President Michael Hainisch .
In 2005, severe damage was found at the Weinzöttl Bridge, which made urgent restoration necessary. This work was carried out in 2007. During this time, it was closed to road traffic with the exception of public buses. The costs were shared with Maschinenfabrik Andritz , as it runs around 500 trains per year over the bridge.
