Catoosa County's Poor-condition bridges carry 7,050 vehicle crossings a day
That is 0.5% of the county's reported daily bridge traffic on 3.5% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 2,350 crossings a day against 13,809 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.

47.7% of Catoosa County's bridges have passed the 50-year mark
41 of the 86 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 53.5% 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 76% of the county's Poor-condition bridge traffic
POST ROAD (M-1110) over I-75, built 1961, carries 5,360 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.
