Hancock County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Hancock County ranks #15 of 16 Maine counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 22.9%). Hancock County, Maine contains 70 public highway bridges. Roughly 21.4% are rated “Good,” 55.7% “Fair,” and 22.9% “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.

Hancock County's Poor-condition bridges carry 45,365 vehicle crossings a day
That is 19.9% of the county's reported daily bridge traffic on 22.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,024 crossings a day against 3,055 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.

65.7% of Hancock County's bridges have passed the 50-year mark
46 of the 70 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 21.4% 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 36.3% of the county's Poor-condition bridge traffic
MAIN ST over UNION RIVER, built 1923, carries 16,449 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 16-bridge count understates how much of the daily burden sits on a single crossing.
