152 public highway bridges tracked in the FHWA National Bridge Inventory: 56.6% rated Good, 42.1% Fair, 1.3% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Deschutes County pairs a top-quartile lowest Poor-condition share among rated counties in the state with a newer 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, Deschutes County ranks #5 of 36 Oregon counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 1.3%). Deschutes County, Oregon contains 152 public highway bridges. Roughly 56.6% are rated “Good,” 42.1% “Fair,” and 1.3% “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 152 NBI-tracked bridges by lowest applicable component rating.
That is 0% of the county's reported daily bridge traffic on 1.3% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 10 crossings a day against 8,716 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 152 of 152 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
44 of the 152 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 56.6% 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.
COYOTE RD NG/BBRG1 over NORTH UNIT CANAL, built 1960, carries 13 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 2-bridge count understates how much of the daily burden sits on a single crossing.
