Morris County's Poor-condition bridges carry 1,991 vehicle crossings a day

That is 5.5% of the county's reported daily bridge traffic on 12.8% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 87 crossings a day against 380 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.

55.3% of Morris County's bridges have passed the 50-year mark

99 of the 179 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 33% 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 37.2% of the county's Poor-condition bridge traffic

K177 HWY over FOUR MILE CREEK, built 1953, carries 740 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 23-bridge count understates how much of the daily burden sits on a single crossing.
