abstract = {This study focuses on the evolution of the Arousa Island Bridge, a critical infrastructure connecting, in northwestern Spain, the Arousa island to the Galician coast. Since its commissioning in 1985, the bridge has experienced damage due to corrosion, culminating in a major repair intervention in 2011 using hybrid galvanic cathodic protection. This repair was essential in addressing identified pathologies and ensuring the safety of the structure. In 2021, additional repairs needed to be completed, and a thorough study and testing campaign was conducted in 2023 which included the extraction of zinc anode samples from the bridge. The present work evaluates the effectiveness of the repair measures implemented since the intervention, with particular attention to corrosion risk and the durability of the cathodic protection system installed to mitigate corrosion risks in the reinforced concrete exposed to a harsh marine environment. A key aspect of this study is the correlation established between the indirect measurements utilized to evaluate zinc consumption within the cathodic protection system and the direct assessment obtained from the extraction of the anodes, which provides a tangible measure of this consumption. The calculated service life was updated with the measurement, and the integrity of the system was assessed.},

abstract = {The Isla de Arousa Bridge, 1980 m long, is the only road access to Isla de Arousa. Built in 1985, this single-cell box girder divided into 40 spans runs entirely over the sea. In response to corrosion damage, the local government decided to make an intervention with an ambitious repair project in 2009. The repair, carried out with three different techniques, aims to collect data for future repairs. In this research the results of rehabilitation and comparison of the evolution of the repairs are described, together with the data on the progression of corrosion and its effect on the life cycle. At the moment, with data from 10 years of protection, both hybrid and galvanic anodes installation have shown effectiveness. Bridge Health index analysis shows that after reparation, the bridge presented a very good condition, and even after 10 years the condition is still good, except for some damaged bearings.},
