The investigated bridge object is part of the A1 highway in Austria. The newly built highway bridge crossing over the Traun River consists of two separate load-bearing structures – one for each driving direction.

As the bridge structure related with the driving direction Vienna – was removed (blown), the newly built structure (driving direction Salzburg) had to be monitored in order to evaluate the impact of the blasting on its structural safety and operability. The comprehensive dynamic analysis – by means of BRIMOS® Structural Health Monitoring – focused on the main bridge.
