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.

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.

Computed over the 252 of 252 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

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.
