Hill County Bridge Snapshot

According to the Federal Highway Administration's 2024 National Bridge Inventory, Hill County ranks #131 of 247 Texas counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 1%). Hill County, Texas contains 405 public highway bridges. Roughly 41% are rated “Good,” 58% “Fair,” and 1% “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.

Hill County's Poor-condition bridges carry 290 vehicle crossings a day

That is 0% of the county's reported daily bridge traffic on 1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 73 crossings a day against 6,017 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.

43% of Hill County's bridges have passed the 50-year mark

174 of the 405 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 41% 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 34.5% of the county's Poor-condition bridge traffic

CR 3323 over ASH CREEK BRANCH, built 2002, carries 100 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 4-bridge count understates how much of the daily burden sits on a single crossing.
