The Fridolinsbrücke is a road bridge that spans the Rhine with two lanes and footpaths on both sides between the city of Bad Säckingen and the municipality of Stein and forms the border between Germany and Switzerland in the middle . The name of the building is Fridolin von Säckingen . On the German side, the bridge is part of the federal highway 518 .
history
As part of a regional link between the German federal road network and the Swiss main road network as well as to relieve the old town of Bad Säckingen and the old wooden bridge , a state treaty was concluded between the Swiss Federal Council and the Federal Republic of Germany on the construction of the new bridge on December 6, 1976 . The canton of Aargau was in charge of project planning and implementation . Construction began on March 1, 1977, and opened on September 22, 1979.
construction
The road route is straight in the area of the structure and has a gradient of 2.4% towards Stein. The Rhine is crossed at an angle of around 82 °. Around 100 m before the Swiss abutment, a trumpet-shaped widening of the carriageway begins for a lane at the intersection with Hauptstrasse 7 on the left bank of the Rhine . For shipping there is a passage on the left bank of the Rhine with a clear width of 80 m and a clearance height of 6.0 m at the highest navigable water level.
The prestressed concrete bridge is 244 m long. It has the continuous beam as a building system in the longitudinal direction . The spans for the three-span road overpass are 106 m in the left edge field, 85 m in the middle field and 53 m in the right edge field.
In the transverse direction, the 12.92 m wide superstructure is designed as a single-cell box girder cross-section with a haunched construction height. The base plate of the box girder is 6.8 m wide. The construction height is 6.25 m above the left river pillar, 3.95 m at the Swiss abutment and 2.80 m at the German abutment. The prestressing consists of internal tendons in the longitudinal and transverse directions . The around 16 m high pillars have massive, constant cross-sections and are built flat on rock.
The bridge superstructure was constructed from south to north in two sections with lengths of 143 m and 101 m on a falsework . The foundations of the river piers were concreted within a pounded construction pit.
Fridolin sculpture
Approximately in the middle of the Fridolinsbrücke on its north side is a bronze sculpture by the Swiss artist Rolf Brem from 1979. The sculpture stands on a rectangular concrete base in which a bronze banner is embedded halfway up. This band runs around each side of the block; on it is written: St. Fridolin founder of Säckingen and patron of the landscape on the Upper Rhine .
State border
The border runs centrally across the Rhine, there is no marking on the bridge. The Swiss and German border clearance takes place in a joint clearance point on German territory.
