Fort Bend County's Poor-condition bridges carry 22,338 vehicle crossings a day

That is 0.2% of the county's reported daily bridge traffic on 2.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 1,117 crossings a day against 11,731 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 794 of 795 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

11.2% of Fort Bend County's bridges have passed the 50-year mark

89 of the 795 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 72.8% 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.

One structure carries 84.6% of the county's Poor-condition bridge traffic

SH 99 over BRAZOS RIVER, built 1994, carries 18,892 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 20-bridge count understates how much of the daily burden sits on a single crossing.
