East Baton Rouge County's Poor-condition bridges carry 411,263 vehicle crossings a day

That is 4.3% of the county's reported daily bridge traffic on 19.7% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 3,844 crossings a day against 15,159 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 542 of 548 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

51.5% of East Baton Rouge County's bridges have passed the 50-year mark

282 of the 548 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 41.8% 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 10.8% of the county's Poor-condition bridge traffic

US0190 over CREEK, built 1960, carries 44,391 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 108-bridge count understates how much of the daily burden sits on a single crossing.
