Railway bridge Oed

The railway bridge in Oed is on the Nuremberg – Schwandorf railway line . It has a four-tiered vault and is a listed building .

Geographical location

The bridge is located at kilometer 38.586 of the Nuremberg-Schwandorf railway at the southern entrance of Oed , in the municipality of Weigendorf in Amberg-Sulzbach in Bavaria . The railway line runs through the narrow Lehenbach valley , as does the AS 38 district road from Weigendorf to Etzelwang and the Etzelbach . Due to the further arc radii that are required for a railway line compared to a road, the railway line crosses the road several times, as well as the stream and changes the valley side. The valley is particularly narrow in the area of ​​the Oed railway bridge .

history

The bridge dates from the construction time of the double-track line, which was opened in 1859. It was built by the Bayerische Ostbahn . The work on the stone of the bridge was carried out by Italian workers.

Building

The bridge was built as a single arch overpass. The road passage is 9.3 meters wide, the maximum headroom is 3.9 meters. The topographically difficult situation meant that the railway had to cross the existing road at an inclined angle. The structurally most stable form of the bridge arch, however, is a span at an angle of 90 degrees. In order to manage with a bridge arch with the smallest possible span despite the inclined angle , the bridge arch was built in five individual, rectangular in plan , directly adjacent to each other with a span of 13.5 meters each, which are each about 1.3 meters offset from one another . This results in an angle for the underpass of the road under the railway, which corresponds to the angle of the two traffic routes to each other.

The two outer sheets were from dolomite brick, the three middle of Dogger - sandstone . So that the arches are firmly connected, two tie rods were placed above the apex of the vault . Visually, the exposed brickwork is based on humped blocks . Since the gradation of the five arches at the bottom view changes the gradation at the apex of the arches from one side to the other, the gradation can only be seen on the right side, while the outer edges of the arches are on the left side of the passage lie in alignment and are not recognizable as individual arches.

The topographical situation was so cramped that the Etzelbach was piped at this point and also passed under the road under the railway line.

Monument protection

The Bavarian State Office for Monument Preservation classifies the bridge as "of outstanding architectural quality" and added it to the Bavarian monument list in 2016 because it fulfills the criteria of Article 1, Paragraph 1 of the Bavarian Monument Protection Act .
