New Mexico 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 New Mexico.

4,035
Public bridges
35.0%
Good condition
4.5%
Poor condition

New Mexico holds 4,035 public highway bridges (#40 of 52 by inventory) with a 4.51% Poor share (#39 of 52 by Poor share).

That is 4.5% 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 14 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.

New Mexico 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: New Mexico has 4,035 bridges and a 4.5% Poor-condition share in the 2024 NBI, rank #14 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.
