Chambers County, Texas contains 152 public highway bridges.

Chambers County's Poor-condition bridges carry 1,165 vehicle crossings a day

That is 0.1% of the county's reported daily bridge traffic on 2% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 388 crossings a day against 12,734 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 152 of 152 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

42.8% of Chambers County's bridges have passed the 50-year mark

65 of the 152 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 47.4% 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 39% of the county's Poor-condition bridge traffic

BAILEY RD over WHITES BAYOU (BARROW SL), built 1976, carries 454 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 3-bridge count understates how much of the daily burden sits on a single crossing.
