Mellingen railway bridge

from Wikipedia, the free encyclopedia
Bridge over the Reuss

The Mellingen railway bridge leads the Zurich - Heitersberg - Lenzburg railway and the WettingenLenzburg line over the Reuss in the canton of Aargau in Switzerland .

history

The bridge was built in 1877 by the Swiss National Railway (SNB) as part of the new railway line from Wettingen to Zofingen . The design came from Moritz Probst and Jules Röthlisberger. The construction company Ott & Cie. , Bern, and Bell Maschinenfabrik in Kriens carried out the single-lane bridge construction with a six-meter-high steel girder with a diamond framework. The roadway is on top of the carrier. Two pillars were made of steel framework and the third of masonry.

In 1932 the Swiss Federal Railways (SBB) had the girder reinforced with the roadway and the iron pillars concreted in.

When the Heitersberg line opened, the SBB replaced the iron truss from 1972 to 1973 with a two-lane composite structure made of a sheet metal girder with a gravel trough made of reinforced concrete. The design from 1972 comes from Basler & Hofmann, Zurich, and the construction was carried out by the steel construction company Zschokke Wartmann AG , Brugg .

situation

The bridge is located 1.5 kilometers northwest of the town of Mellingen above the Reuss, which forms the municipal boundary between Mellingen and Wohlenschwil . At this point, the river breaks through a still very pronounced terminal moraine (or the Gruemet central moraine ) of the former Reuss glacier in a narrow, around 50 meters deep gorge, which is why only a relatively short bridge 193 meters long was necessary for the construction of the railway line. To the right of the river is the abutment of the bridge on the Gruemet hill in the municipality of Mellingen near the junction of the two lines to Zurich and Baden.

The old Mellingen train station was north of the Gruemet on the NOB line, the new Mellingen Heitersberg train station is between the junction and the west portal of the Heitersberg tunnel , next to the main road from Mellingen to Fislisbach . The old station now serves as a loading station for the SOCAR tank farm in Mellingen.
