history

Rhine bridge around 1650

A ford near Eglisau was probably already there in Roman times . A first wooden bridge was built around 1240 on the initiative or with the support of the Barons von Tengen . The existence of the Rhine bridge near Eglisau, an open wooden bridge with about five pile yokes, which led from the church to the former Eglisau Castle , was mentioned in a document in 1249. A renewal of the bridge after a flood is recorded for 1542. It was a covered and in some areas boarded wooden bridge, some with open fore bridges, which had four brick pillars and a wooden pile yoke. In particular, the undercutting of the bridge foundations during floods, but also ice drift in the winter of 1789, led to repairs to the structure, which were paid for with bridge tolls. During the Thirty Years War , a drawbridge was installed in the first bridge opening on the Zurich side.

In 1799, French troops dismantled the Rhine bridge while retreating from the battle of Stockach, which they lost in the Second Coalition War . The following Austrian troops built a makeshift bridge and, below Eglisau, a ship bridge. After the defeat in the second battle of Zurich , the Austrian and Russian troops used the Rhine crossing at Eglisau for their retreat and Russian troops destroyed the makeshift bridge on September 26, 1799. In the middle of 1800 the French troops rebuilt a temporary bridge . After the end of the war, the Canton of Zurich ordered a new bridge to be built in 1804. The building, a covered wooden bridge with a bricked river pillar, was built in 1811 by the commissioned state architect Conrad Stadler at the same location as the previous bridges. The structure had a two-arched wooden truss with a larger and a smaller river opening, with a maximum span of 45 meters. There was a 4.0 meter wide carriageway and sidewalks on both sides.

As part of the Rheinsfelden river power plant , which was built from 1915 to 1920 , the Rhine was dammed by around 6.5 meters in the area of ​​the wooden bridge. This required the demolition of the old bridge and a replacement bridge, which was built between 1914 and 1918 in a better location around 300 meters downstream based on a design by the Locher company and the Pfister brothers' architectural office . The structure was opened to traffic on September 14, 1919. Initially there was a 7 meter wide carriageway and two walkways 1.5 meters wide on both sides. In 1987 the western sidewalk was removed and the eastern sidewalk widened to 2.0 meters and the carriageway slab to 8.0 meters. In addition, a pedestrian underpass was built on the southern abutment. In 1995–96 there was another renovation with a new pedestrian walkway made of steel and wood, which was mounted on the side so that the old sidewalk could be used as a cycle path.

In the 1980s there were plans to bypass the city of Eglisau over a large area with a 350 meter long, four-lane high bridge to cross the Rhine, parallel to the railway bridge . However, the project was rejected in a cantonal referendum on March 10, 1985 with a clear majority with 37 percent participation.

construction

Rheinbruecke Eglisau

The approximately 130-meter-long arch bridge from 1919 has a concrete vault with front walls covered with concrete. It is clad with a small-format, light natural stone. The bridge has three openings with a clear width of 40.7 meters each. With a pillar width of around 18 meters and a thickness of 4.3 meters, the center distance of the river piers is 45 meters. The 10.8 meter wide bridge has a 10 meter wide deck and balustrades 0.4 meter wide on both sides. The pillars were founded with caissons at a depth of up to 30 meters below the upper edge of the carriageway. The caissons are 18 meters long and 7.9 meters wide and were founded in the rock with the help of an open construction pit, secured by sheet piling .
