Jefferson County, Texas contains 457 public highway bridges.

Jefferson County's Poor-condition bridges carry 134,131 vehicle crossings a day
That is 2.2% of the county's reported daily bridge traffic on 1.5% of its bridges: Poor-condition structures carry more traffic than their share of the inventory. Each Poor bridge averages 19,162 crossings a day against 9,568 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.

54.7% of Jefferson County's bridges have passed the 50-year mark
250 of the 457 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 48.4% 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 66.8% of the county's Poor-condition bridge traffic
IH 10 over 11TH ST, built 1958, carries 89,604 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 7-bridge count understates how much of the daily burden sits on a single crossing.
