Masonry bridges, predominantly constructed from stone or brick, were a common feature of bridge engineering during the 18 th and 19 th centuries. However, these historic bridges are still in use today, but they are at risk due to various extreme climate conditions. Thus, these bridges are vulnerable to damage and needy for investigation. This paper offers an in-depth analysis of the projected impacts of fluvial flooding stemming from climate change on a number of masonry arch bridge structures located in county Offaly, Ireland. It evaluates bridge resilience by examining estimated flood levels alongside the overall condition of the structures. These assessments play a crucial role in determining the load-bearing capacity of the bridges and whether adjustment factors should be implemented. Particularly for bridges situated on primary and secondary roads with consistent heavy goods vehicle (HGV) traffic, the potential decrease in load-bearing capabilities warrants significant consideration. This study highlights concerns regarding the resilience of these historic structures and presents a valid argument regarding their suitability for contemporary environmental conditions and present-day activities.
