Örnsköldsvik bridge (case study)

The concrete trough railway bridge in Örnsköldsvik was built in 1955 with two spans and a length of 24 m. It was decommissioned due to the building of a new railway, the Bothnia Line. It was assessed and tested to failure in the European FP6 project Sustainable Bridges, Bien et al. (2007), Puurula et al, (2015), Sas et al. (2012).
