Infrastructures　in　coastal　areas　are　often　prone　to　several　hazards,　and　thus　the　elaboration　of　effective　risk　management　plans　in　such　zones　are　possible　if　all　relevant　threats　are　considered　and　analyzed.　In　this　context,　the　assessment　of　the　corrosion　hazard　attributable　to　airborne　chlorides　is　of　utmost　importance　since　the　resulting　deterioration　phenomena　can　heavily　jeopardize　both　reliability　and　resilience　of　the　infrastructures.　Therefore,　this　contribution　aims　at　proposing　the　preliminary　version　of　a　possible　framework　for　the　elaboration　of　corrosion　hazard　maps　at　regional　scale　for　coastal　areas,　with　focus　on　reinforced　concrete　bridges.　The　proposed　approach　encompasses　three　main　steps.　First,　the　relevant　stock　of　infrastructures　vulnerable　to　chloride‐induced　corrosion　is　identified　and　quantified.　This　requires　the　collection　of　relevant　features,　such　as　construction　type,　position,　and　age.　Environmental　conditions　are　examined　next,　including　data　about　sea　waves　and　salinity,　wind,　temperature,　humidity,　rainfall,　and　chloride　deposition　rate.　Finally,　the　corrosion　hazard　is　estimated　in　probabilistic　sense.　The　proposed　methodology　is　presented　together　with　the　preliminary　results　obtained　from　a　relevant　case　study.
