The Europa Bridge near Innsbruck – Austria, opened in 1963, is one of the main alpine north-south routes for urban and freight traffic. Currently the bridge is stressed by more than 40000 motor vehicles per day. The combination of measuring and analytical calculation over the past years has led to detailed system identification. Due to the requirement to assess the prevailing vibration intensities with regard to fatigue problems and possible damage, a permanent measuring system has been installed in 2003.
