The Rhine Bridge Hemishofen is a bridge that spans the Rhine near Hemishofen in Switzerland . The road bridge with two lanes and a footpath and cycle path dates from 1980. It crosses Hauptstrasse 332, which begins in the canton of Schaffhausen on the German-Swiss border near Ramsen SH and ends at Hauptstrasse 13 in the canton of Thurgau . The structure is arranged upstream parallel to the historic railway bridge .
history
The first considerations regarding a Rhine crossing for road traffic at Hemishofen were made in 1933, ten years later there were plans for a road north of the railway line. In 1968, the canton of Schaffhausen presented the road construction project with the Hemishofen bypass and a new bridge over the Rhine to connect to the road network on the left bank of the Rhine. Among other things, this should relieve the Rhine bridge from Stein am Rhein from through traffic. The postponed construction of the then Europastrasse 70 (later renumbered Europastrasse 41 ) with a new bridge over the Rhine in Schaaren near Diessenhofen also indicated an increase in traffic. Despite resistance on site, due to the expected traffic loads, the people agreed to the traffic project with a Rhine bridge above the existing railway bridge at the end of 1976. A public project competition for the new Rhine bridge near Hemishofen was organized, with the engineering office Wüst, Stucki and Hofacker from Schaffhausen / Zurich being awarded first prize. The bridge should be as light and transparent as possible. The beam construction and position of the slender river piers were chosen in relation to the old railway bridge. Bridge construction began in January 1978. The inauguration ceremony for the bridge and bypass took place on August 30, 1980. The construction costs amounted to 8.4 million francs.
construction
The structure consists of a 345 m long prestressed concrete structure with five fields. It has a continuous beam as a structural system in the longitudinal direction . The spans from north to south are 67.0 m, 2 × 75.0 m, 71.0 m and 57.0 m. In the transverse direction there is a single-cell box girder cross-section with a floor slab width of 4.5 m and a deck slab width of 12.1 m. The construction height of the superstructure is a constant 3.25 m. The pillars with upper external dimensions of 4.56 × 2.0 m have a massive reinforced concrete cross-section . In relation to the low water they have a height of 23 m, the cross-section width decreases with the height in a ratio of 1:40. The foundation of the pillars consists of six bored piles with a diameter of 1.5 m, reaching 23 m into the river bed.
In order to develop the construction site, the construction consortium built footbridges in the Rhine from both banks. The 4.8 m wide inner box of the superstructure was constructed with a prop scaffolding, for which additional auxiliary piers in the Rhine were necessary. The laterally protruding carriageway slab was then manufactured using a so-called bracket car.
