Herøysund bridge is a post-tensioned bridge located in Nordland Fylkeskommune. Recent inspections have identified corrosion in the tendons of the post-tension system. The bridge was recently strengthened to extend the service life of the structure. A replacement of the bridge has been planned and the old bridge will be demolished. This case constitutes an excellent case study to try to improve current engineering practice in structural assessment of existing structures, by applying the latest scientific developments. Nordland Fylkeskommune together with Statens Vegvesen consider that the in-depth evaluation of this bridge can bring additional knowledge and better understanding of a structure’s state, deterioration mechanism and structural safety. This will contribute towards the refined and improved structural assessment procedures.
