Cameron County's Poor-condition bridges carry 1,926 vehicle crossings a day

That is 4.8% of the county's reported daily bridge traffic on 6.6% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 482 crossings a day against 435 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.

41.9% of Cameron County's bridges have passed the 50-year mark

26 of the 62 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 43.5% 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.

One structure carries 81.6% of the county's Poor-condition bridge traffic

SR 155-PA 155 over PORTAGE CREEK, built 1941, carries 1,571 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 5-bridge count understates how much of the daily burden sits on a single crossing.
