Shelby County Bridge Snapshot
According to the Federal Highway Administration's 2024 National Bridge Inventory, Shelby County ranks #235 of 247 Texas counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 4.5%). Shelby County, Texas contains 176 public highway bridges. Roughly 49.4% are rated “Good,” 46% “Fair,” and 4.5% “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.

Shelby County's Poor-condition bridges carry 1,415 vehicle crossings a day
That is 0.5% of the county's reported daily bridge traffic on 4.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 177 crossings a day against 1,571 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 176 of 176 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
30.1% of Shelby County's bridges have passed the 50-year mark
53 of the 176 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 49.4% 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 52.5% of the county's Poor-condition bridge traffic
FM 139 over TENAHA BAYOU, built 1967, carries 743 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 8-bridge count understates how much of the daily burden sits on a single crossing.
