Oxford County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Oxford County ranks #9 of 16 Maine counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 17.5%). Oxford County, Maine contains 252 public highway bridges. Roughly 25% are rated “Good,” 57.5% “Fair,” and 17.5% “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.

Oxford County's Poor-condition bridges carry 65,556 vehicle crossings a day

That is 16.4% of the county's reported daily bridge traffic on 17.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,490 crossings a day against 1,824 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 252 of 252 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

58.7% of Oxford County's bridges have passed the 50-year mark

148 of the 252 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 25% 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 17.8% of the county's Poor-condition bridge traffic

MAIN ST over TANNERY (BIRD) BROOK, built 1929, carries 11,655 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 44-bridge count understates how much of the daily burden sits on a single crossing.
