Mississippi 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 Mississippi.

Public bridges
55.1%
Good condition
6.0%
Poor condition

Mississippi holds 16,739 public highway bridges (#14 of 52 by inventory) with a 6.03% Poor share (#26 of 52 by Poor share).

That is 6.0% 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 27 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.

Mississippi in the national condition pattern

Each point is a state or territory in the FHWA NBI; the highlighted point is this profile.

Inventory size and Poor-condition share are different measures: Mississippi has 16,739 bridges and a 6.0% Poor-condition share in the 2024 NBI, rank #27 of 54 jurisdictions ordered from the lowest share upward. The dashed comparisons mark the national average state rate and the midpoint of the plotted inventory range; neither is a live safety or closure threshold.
