Recent extreme flood events in Slovenia have highlighted the vulnerability of the bridge network to scour-related stability issues, leading to the failure of several structures. In response to these emerging challenges, this study introduces a streamlined approach for assessing the vulnerability of bridge networks to flood-related risks. Developed within the CROSScade project, this research addresses the flood-related risks of bridges spanning the Sava River near the border between Slovenia and Croatia. A key innovation of this study is the development of a rapid network-level assessment methodology, which allows evaluation of multiple bridges with only limited input data requirements. This methodology facilitates the identification of the most critical bridges, saving time and resources on detailed examination of all bridges in the network. This research aims to equip bridge owners and infrastructure managers with essential insights into their structures' susceptibility to scour and flood hazards. Despite the simplifications inherent in the methodology, the findings can significantly contribute to developing more robust management and mitigation strategies. This, in turn, is expected to enhance the resilience of critical transport networks against natural hazards, particularly in flood-prone regions.
