FHWA National Bridge Inventory condition ratings and structural-deficiency flags
Tobias Renner leads how BridgeSafety reads and presents the FHWA National Bridge Inventory. The role decides which NBI fields and annual vintage each bridge, state, and county page uses, documents how deck, superstructure, and substructure condition ratings roll up into a single readable grade, and triages corrections. Condition grades, sufficiency ratings, and structural-deficiency flags are drafted with AI assistance and editorially reviewed against the underlying FHWA NBI release before publication, and every value links back to its source.
