149 public highway bridges tracked in the FHWA National Bridge Inventory: 57.7% rated Good, 34.2% Fair, 8.1% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Chelan County posts a higher-than-median Poor-condition share among rated counties in the state across mid-size 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, Chelan County ranks #28 of 39 Washington counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 8.1%). Chelan County, Washington contains 149 public highway bridges. Roughly 57.7% are rated “Good,” 34.2% “Fair,” and 8.1% “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 149 NBI-tracked bridges by lowest applicable component rating.
That is 14.3% of the county's reported daily bridge traffic on 8.1% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 5,943 crossings a day against 2,618 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.

75 of the 149 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 57.7% 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.
US 2 over COLUMBIA RIVER, built 1975, carries 25,688 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 12-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 71,315 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.

The 5 Washington counties nearest Chelan County in number of bridges, with their condition splits. Its 8.1% Poor share is the 5th-lowest of these 6. Its average build year of 1974 against a peer-group mean of 1974 is in line with the group.
