90 public highway bridges tracked in the FHWA National Bridge Inventory: 43.3% rated Good, 52.2% Fair, 4.4% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Greenlee County pairs a higher-than-median Poor-condition share among rated counties in the state with an older average build year than the state inventory.
Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Greenlee County ranks #14 of 15 Arizona counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 4.4%). Greenlee County, Arizona contains 90 public highway bridges. Roughly 43.3% are rated “Good,” 52.2% “Fair,” and 4.4% “Poor.” Poor means the lowest applicable deck, superstructure, substructure, or culvert rating is 4 or below on the 0–9 NBI scale. It is a condition category, not a live safety or closure decision.
Responsible agencies inspect covered bridges on risk-based intervals under current NBIS rules and submit inventory data to FHWA annually. The list below shows every NBI-tracked bridge in the county.

Share of 90 NBI-tracked bridges by lowest applicable component rating.
That is 1.6% of the county's reported daily bridge traffic on 4.4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 602 crossings a day against 2,139 for a Good-condition one. A Poor rating is a condition category, not a closure or a live safety judgement; it means the lowest applicable component rating is 4 or below.

67 of the 90 bridges with a recorded construction year were built in 1974 or earlier. Age alone is not a defect: a well-maintained older bridge can rate Good, and 43.3% of this county's inventory does. Even so, this older cohort is the population from which future Poor ratings are drawn, which is why the age profile below matters alongside the condition split above.

US 191;FAU 9512 over Industrial Plant; FAS 21, built 1943, carries 1,048 vehicles a day, the most of any Poor-rated structure here. The county's Poor-condition exposure is concentrated rather than evenly spread, so the 4-bridge count understates how much of the daily burden sits on a single crossing.
