Lee County's Poor-condition bridges carry 58,400 vehicle crossings a day

That is 0.8% of the county's reported daily bridge traffic on 0.8% of its bridges: Poor-condition structures carry the same share of traffic than their share of the inventory. Each Poor bridge averages 19,467 crossings a day against 18,433 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.

33.8% of Lee County's bridges have passed the 50-year mark

132 of the 391 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 75.4% 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 73.6% of the county's Poor-condition bridge traffic

DEL PRADO BLVD NB over LIDO CANAL, built 1965, carries 43,000 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.
