Orange County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Orange County ranks #70 of 100 North Carolina counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 7.9%). Orange County, North Carolina contains 189 public highway bridges. Roughly 38.1% are rated “Good,” 54% “Fair,” and 7.9% “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.

Orange County's Poor-condition bridges carry 125,010 vehicle crossings a day

That is 6.5% of the county's reported daily bridge traffic on 7.9% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 8,334 crossings a day against 5,077 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.

37% of Orange County's bridges have passed the 50-year mark

70 of the 189 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 38.1% 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 26.2% of the county's Poor-condition bridge traffic

I85S over SR1713, built 1958, carries 32,750 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 15-bridge count understates how much of the daily burden sits on a single crossing.
