Morgan County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Morgan County ranks #37 of 92 Indiana counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 4%). Morgan County, Indiana contains 252 public highway bridges. Roughly 50.4% are rated “Good,” 45.6% “Fair,” and 4% “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.

Morgan County's Poor-condition bridges carry 7,042 vehicle crossings a day
That is 0.7% of the county's reported daily bridge traffic on 4% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 704 crossings a day against 5,653 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.

35.3% of Morgan County's bridges have passed the 50-year mark
89 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 50.4% 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 53.1% of the county's Poor-condition bridge traffic
OLD SR 37 over BLUFF CREEK, built 1930, carries 3,740 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 10-bridge count understates how much of the daily burden sits on a single crossing.
