County profile · official public datasets
916 public highway bridges tracked in the FHWA National Bridge Inventory: 38.9% rated Good, 57.3% Fair, 3.8% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Fresno County posts a top-quartile lowest Poor-condition share among rated counties in the state across large county bridge 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, Fresno County ranks #9 of 58 California counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 3.8%). Fresno County, California contains 916 public highway bridges. Roughly 38.9% are rated “Good,” 57.3% “Fair,” and 3.8% “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 916 NBI-tracked bridges by lowest applicable component rating.
That is 2.7% of the county's reported daily bridge traffic on 3.8% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 7,684 crossings a day against 15,630 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.
Computed over the 916 of 916 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
550 of the 916 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 38.9% 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.
Cutoff derives from the 2024 release year minus a 50-year design life. Source: FHWA National Bridge Inventory, 2024 release.
STATE ROUTE 41 over O STREET, built 1974, carries 76,000 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 35-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 268,953 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.

What this shows Construction peaked in the 1960s, when 165 of the county's bridges still in the inventory were built, which is 18% of those with a recorded year. That cohort is now 55 to 64 years old in the 2024 inventory. Its average build year (1969) matches the California average (1970).
The 5 California counties nearest Fresno County in number of bridges, with their condition splits. Its 3.8% Poor share is the 4th-lowest of these 6. Its average build year of 1969 against a peer-group mean of 1974 is 5 years older.
