County profile · official public datasets
223 public highway bridges tracked in the FHWA National Bridge Inventory: 35.4% rated Good, 64.6% Fair, 0% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Brown County pairs a top-5% lowest Poor-condition share among rated counties in the state with an older average build year than the state inventory.
Poor is an FHWA condition category from the lowest applicable component rating (4 or below), not a live crossing-safety or closure decision. Rankings cover counties with at least five public highway bridges.
According to the Federal Highway Administration's 2024 National Bridge Inventory, Brown County ranks #5 of 247 Texas counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 0%). Brown County, Texas contains 223 public highway bridges. Roughly 35.4% are rated “Good,” 64.6% “Fair,” and 0% “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.

Share of 223 NBI-tracked bridges by lowest applicable component rating.
174 of the 223 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 35.4% 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.
