Frequently asked questions
How many bridges in New Mexico are in poor condition?
172 of New Mexico's 4,033 inventoried highway bridges are rated in poor condition (4.3%) in the 2025 National Bridge Inventory. 'Poor' is FHWA's classification for a bridge whose deck, superstructure, or substructure is rated 4 or lower on the 0-9 scale; it was formerly called 'structurally deficient'.
Are the poor-rated bridges in New Mexico safe to drive on?
A poor rating flags advanced deterioration that needs repair or close monitoring; it does not by itself mean a bridge is unsafe. Bridges judged unsafe are closed or restricted to lighter loads by the owner. Inspections continue on all open bridges, generally at least every 24 months under the National Bridge Inspection Standards.
