Public highway bridges in Louisiana
State profile · Above median Poor share
Louisiana bridge safety
According to the Federal Highway Administration's 2024 National Bridge Inventory, condition ratings, load ratings, and Poor-condition shares for every public highway bridge in Louisiana.
- 12,698
- Public bridges
- 38.7%
- Good condition
- 11.5%
- Poor condition
Louisiana holds 12,698 public highway bridges (#24 of 52 by inventory) with a 11.48% Poor share (#8 of 52 by Poor share).
That is 11.5% of the state's inventory, against an average of 7.5% across the 54 states and territories with Poor-rated bridges on file, which places it 45 of 54 ordered from the lowest Poor share upward. A bridge is rated Poor when its weakest applicable component scores 4 or below on the inspecting agency's 0-9 scale, so the category is a maintenance and funding signal rather than a closure order or a live crossing-safety verdict.
