County profile · official public datasets
991 public highway bridges tracked in the FHWA National Bridge Inventory: 57.8% rated Good, 41.3% Fair, 0.9% Poor.
The verdict
According to the Federal Highway Administration's 2024 National Bridge Inventory.
Denton County pairs a higher-than-median Poor-condition share among rated counties in the state with a newer 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, Denton County ranks #129 of 247 Texas counties with at least 5 public highway bridges on Poor-condition share (lower share ranks better; currently 0.9%). Denton County, Texas contains 991 public highway bridges. Roughly 57.8% are rated “Good,” 41.3% “Fair,” and 0.9% “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 991 NBI-tracked bridges by lowest applicable component rating.
That is 1% of the county's reported daily bridge traffic on 0.9% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 14,140 crossings a day against 13,125 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 989 of 991 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.
221 of the 991 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 57.8% 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.
IH 35 NBML over CLEAR CREEK, built 1958, carries 33,174 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 9-bridge count understates how much of the daily burden sits on a single crossing.
Share is of the 127,256 daily crossings on Poor-rated bridges that report a traffic count. Source: FHWA National Bridge Inventory, 2024 release.
