Reinforced　concrete　arch　bridges　represent　iconic　and　enduring　engineering　marvels　that　often　stand　the　test　of　time.　However,　their　long-term　durability　faces　an　increasing　threat　from　the　insidious　process　of　corrosion.　This　review　paper　offers　a　comprehensive　analysis　of　the　corrosion＇s　effects　on　reinforced　concrete　arch　bridges.　It　explores　corrosion　mechanisms,　their　implications　for　structural　integrity,　assessment　techniques,　mitigation　strategies,　and　recent　research　advancements.
