Providence County's Poor-condition bridges carry 1,734,366 vehicle crossings a day

That is 15.8% of the county's reported daily bridge traffic on 16.2% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 22,524 crossings a day against 27,007 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.

62% of Providence County's bridges have passed the 50-year mark

295 of the 476 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 23.3% 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 9% of the county's Poor-condition bridge traffic

I-95 NB & SB over THURBERS AV, built 1963, carries 156,790 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 78-bridge count understates how much of the daily burden sits on a single crossing.
