Albany County, Wyoming contains 124 public highway bridges. Roughly 33.1% are rated “Good,” 65.3% “Fair,” and 1.6% “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.

Albany County's Poor-condition bridges carry 7,716 vehicle crossings a day
That is 1.8% of the county's reported daily bridge traffic on 1.6% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 3,858 crossings a day against 2,295 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 124 of 124 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
59.7% of Albany County's bridges have passed the 50-year mark
74 of the 124 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 33.1% 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 80.4% of the county's Poor-condition bridge traffic
I-80 WBL over CR 57 (Dutton Creek Rd), built 1969, carries 6,206 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.
