FHWA NBI record, refreshed with each annual release.
POOL ROAD in Carbon, Pennsylvania sits above 8% of rated Pennsylvania bridges on inventory load rating (21 t), while its 1970 build year is earlier than 27% of Carbon's recorded-year cohort (134 bridges).
POOL ROAD in Carbon, Pennsylvania is rated Poor in the FHWA's 2024 National Bridge Inventory. Built in 1970, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 4.
