Tennessee 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 Tennessee.

20,379
Public bridges
42.5%
Good condition
4.4%
Poor condition

Tennessee holds 20,379 public highway bridges (#10 of 52 by inventory) with a 4.41% Poor share (#41 of 52 by Poor share).

That is 4.4% 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 12 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.

Tennessee 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: Tennessee has 20,379 bridges and a 4.4% Poor-condition share in the 2024 NBI, rank #12 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.
