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.

Lincoln County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Lincoln County ranks #23 of 39 Washington counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 6.1%). Lincoln County, Washington contains 180 public highway bridges. Roughly 56.7% are rated “Good,” 37.2% “Fair,” and 6.1% “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. Use the “Sort by” controls to change the ordering, and click any row for its reported inspection date, traffic count, and condition fields.

Lincoln County's Poor-condition bridges carry 11,500 vehicle crossings a day

That is 9.9% of the county's reported daily bridge traffic on 6.1% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 1,045 crossings a day against 312 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 180 of 180 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

62.8% of Lincoln County's bridges have passed the 50-year mark

113 of the 180 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 56.7% 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.

One structure carries 90.5% of the county's Poor-condition bridge traffic

I-90 over DOERSCHLAG RD, built 1968, carries 10,407 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 11-bridge count understates how much of the daily burden sits on a single crossing.
