West Baton Rouge County, LA

73 public highway bridges

West Baton Rouge County Bridge Snapshot

West Baton Rouge County, Louisiana contains 73 public highway bridges in the FHWA National Bridge Inventory. Roughly 30.1% are rated “Good,” 39.7% “Fair,” 9.6% “Poor,” and 9.6% 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 LA 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.
