Prince George's County's Poor-condition bridges carry 186,683 vehicle crossings a day

That is 0.9% of the county's reported daily bridge traffic on 3.1% of its bridges: Poor-condition structures carry less traffic than their share of the inventory. Each Poor bridge averages 10,371 crossings a day against 35,515 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 576 of 576 bridges in this county that report an average daily traffic count. Source: FHWA National Bridge Inventory, 2024 release.

53.6% of Prince George's County's bridges have passed the 50-year mark

309 of the 576 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 36.6% 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 25% of the county's Poor-condition bridge traffic

MD 4 WBR over MD 717, built 1959, carries 46,652 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 18-bridge count understates how much of the daily burden sits on a single crossing.
