Public highway bridges in New Mexico
State profile · Below median Poor share
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 vs nearby ranks
Adjacent states by Poor-condition share (lower share = better)
States are ranked by the share of bridges whose lowest applicable component rating is 4 or below. This describes recorded condition; it does not measure funding effectiveness or live crossing safety. States here sit immediately above and below New Mexico on the same metric.
