W4 Steyrermühl

Austria

The bridge object is part of the A1 highway and was constructed in 1959. As the bridge structure – related with the driving direction Salzburg – was removed (blown) in 2010, the impact of this blasting on the remaining structure (driving direction Vienna) was evaluated in order to ensure its structural safety and operability. The investigation was focused on the primary load-bearing structure (arch).
