Caroline County, MD

70 public highway bridges

Caroline County Bridge Snapshot

Caroline County, Maryland contains 70 public highway bridges in the FHWA National Bridge Inventory. Roughly 27.1% are rated “Good,” 57.1% “Fair,” 8.6% “Poor,” and 8.6% are classified as structurally deficient — the federal designation for spans whose deck, superstructure, or substructure has been rated 4 or below on the 0–9 NBI scale. Structurally deficient does not mean unsafe to cross; it means the bridge is on the priority list for repair or replacement.

Inspections in MD are conducted by certified engineers from the state Department of Transportation on a 24-month cycle, and results are reported back to the FHWA each spring. The list below shows every NBI-tracked bridge in the county, sorted by inventory load rating. Use the “Sort by” controls to surface the lowest-rated spans first, and click any row for full inspection history, traffic counts, and condition trends.
