The Sauertal Bridge is a 1195 m long motorway bridge on the federal motorway 64 .
The structure spans the Sauer valley with the border between Germany and Luxembourg at a height of a maximum of 98 m near Wasserbillig above the town of Mesenich . In the course of the bridge, the motorway route has a radius of 2000 m and a longitudinal incline of 1%. The girder bridge was built with a joint superstructure for both carriageways between 1984 and 1987.
superstructure
The bridge has a steel superstructure with a constant height and the continuous beam as a structural system. The total span of the eleven-span bridge is 1195.0 m. The field widths, viewed from east to west, are 75 m in the edge field, 90.0 m in the next field, 125.0 m in the following four openings, 150.0 m above the Sauer, 90.0 m in two further openings and again 75.0 m in the western edge field.
In the transverse direction, the main girder of the bridge is a single-cell box girder with an orthotropic deck slab 27 m wide and 3.8% inclined . The floor plate is 8.87 m wide and horizontal. This results in a construction height of 5.0 m on one side of the footbridge and 5.34 m on the other side. The vertical web plates are arranged at a distance of 8.87 m. Cross beams at a distance of 4.16 to 4.5 m as well as diagonal struts at twice the distance support the 9.07 m cantilevered carriageway construction.
Assembly
The superstructure was assembled behind the eastern abutment in 68 shots. Each shot was delivered in eight segments. The steel superstructure was installed using the incremental launching method with 21 pushing cycles. In order to be able to bridge the large field widths without assembly supports, the superstructure was spanned with the help of a 58 m high pylon at a distance of 120 m from the tip of the porch.
