This volume gathers the latest advances, innovations, and applications in the field of arch bridges, as presented at the 11th International Conference on Arch Bridges (ARCH25), held in Genoa, Italy, on September 30 - October 3, 2025. Topics include timber - masonry - stone - steel concrete arch bridges, design – analysis - assessment, construction - rehabilitation - maintenance – monitoring, preservation, experimental techniques for material characterization and structural identification, hydraulic and hydrogeological risk for arch bridges, seismic analysis and risk for arch bridges, bridge management systems: from SHM to decision making processes, structural optimization and robustness, sustainability of arch bridges, numerical modelling and BIM for design and maintenance, heritage arch bridges. The contributions were selected by a rigorous peer-review process, and offer an extensive and multidisciplinary overview of the research in the field of biosystems engineering for sustainable agriculture.
