The Rheinbrücke Diepoldsau , also known locally as the Tram Bridge, is a road bridge in the Swiss municipality of Diepoldsau in the part of the Rhine Valley that belongs to the canton of St. Gallen .
location
Diepoldsau is located on the west bank of the Old Rhine , which runs in a loop to the east and forms the border with Austria . Since the Diepoldsauer Rhine breakthrough in the course of the Rhine regulation , the place has been on the east bank of the 1923 newly built, straightened and canalized Alpine Rhine .
Since then, the bridge has been the most important connection between Diepoldsau and the mainland of Switzerland , along with the smaller Rietbrücke on Oberrieterstrasse. It lies in the extension of the tramway through which the electric Heerbrugg – Diepoldsau tram used to go .
description
In the years 1911–1913 a steel truss bridge was built for the future Rhine cut. The Heerbrugg-Diepoldsau tram had been a side branch of the Altstätten – Berneck tram since October 12, 1915 and led over this bridge, which is therefore also known as the tram bridge and is still used today. This tram operated by the Rheintalische Trassenbahnen was replaced on March 3, 1956 by a bus line. This tram bridge was dilapidated and had to be replaced by a new building.
From 1983 to 1985, a two-lane bridge, each with a walkway in the form of a cable-stayed bridge , was therefore put into practice for the first time a concept developed by René Walther and his colleagues, according to which a stable and largely vibration-free bridge with a simple thin concrete slab in Connection with a large number of side-mounted stay cables can be realized. The bridge was planned by Bänziger + Köppel + Partner , who also had the construction management.
The main opening of the bridge between the two pylons standing directly on the river bank has a span of 97 m, the two side openings above the flood bed have a span of 40.5 m each. On the western side is a foreland bridge, the three fields of which are supported by concrete slabs, on the eastern side one field is also supported by a concrete slab and the abutment in the dike. The structure is 250 m long and has spans of 15 + 18 + 19.5 + 40.5 + 97 + 40.5 + 19.5 m.
The pylons have a height of 28.7 m above the roadway. Their reinforced concrete posts are connected to one another by cross bars below the bridge deck and below the peaks. However, the bridge deck does not rest on the lower crossbar, it only hangs as a floating deck on the 7 or a total of 56 stay cables.
The 14.5 m wide bridge panel consists of a massive prestressed concrete slab that was built in cantilever construction with the bracing by the final stay cables. It is 0.55 m thick along the center line and decreases to 0.36 m towards the edges. From the outside, however, this is hardly noticeable, as the outer boundary of the walkways is formed by a concrete wall.
The new cable-stayed bridge was opened on 30./31. Inaugurated on August 1st and September 1st, 1985 with a village festival.
