The bridge, erected in the year 2000, is an integral part of the track upgrade of Austrian Federal Railways. The design and realization of the project was done by the Austrian HL AG. The bridge consists of a chain of 5 single supported structures, each having a span of 40,0 m. The total length of the structure is 200,0 m. The deck width is sufficient to bear to parallel tracks for the high speed railway traffic. Each single supported structure completely is equipped with internal prestressing, where the main part of tendons is located in the massive 80 cm thick concrete webs.

In the framework of an Austrian research project focused to noise emission and vibration transmission a work package was related to the global and local vibration behavior of railway bridges. In order to study the dynamic characteristic of the structure accurately a combined approach consisting of forced and ambient vibration testing was designed. In parallel a finite element simulation was prepared to compare the results from numerical and experimental testing.
