FHWA NBI record, refreshed with each annual release.
PERIMETER PATROL R in Prince George's, Maryland sits above 15% of rated Maryland bridges on inventory load rating (33 t), while its 1969 build year is earlier than 53% of Prince George's's recorded-year cohort (576 bridges).
PERIMETER PATROL R in Prince George's, Maryland is rated Good in the FHWA's 2024 National Bridge Inventory. Built in 1969, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 7. The lowest applicable rating sets the federal condition category, so this Good result describes the weakest reported component rather than the structure as a whole. No NBI category is a closure decision or a live crossing-safety verdict.
