DUVALL BRIDGE ROAD in Anne Arundel, Maryland sits above 2% of rated Maryland bridges on inventory load rating (16 t), while its 1907 build year is earlier than 100% of Anne Arundel's recorded-year cohort (389 bridges).
DUVALL BRIDGE ROAD in Anne Arundel, Maryland is rated Fair in the FHWA's 2024 National Bridge Inventory. Built in 1907, it carries 3 rated components on the inspecting agency's 0-9 scale, and its weakest reported component scores 6.

No NBI category is a closure decision or a live crossing-safety verdict.
