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 continuous composite beam with 5 spans. The total length of the structure is 274,0 m. The deck width is sufficient to bear to parallel tracks for the high speed railway traffic. The bridge plan view is slightly curved; therefore the bridge must bear high transversal loads. The high design speed of the track requires dynamic investigations for the structure.

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 to study the sound emission radiated by steel structures. A detailed monitoring concept was implemented, consisting of ambient and forced vibration testing of the global structure, testing of the steel webs and measurement of the related noise emission. Using this data, an extensive comparison between the noise radiation of steel and concrete bridges was performed.
