St. Martin County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, St. Martin County, Louisiana contains 116 public highway bridges. Roughly 32.8% are rated “Good,” 50.9% “Fair,” and 8.6% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale.
