Missouri vs nearby ranks
Adjacent states on the structurally deficient leaderboard (lower share = better)
States are ranked by share of bridges flagged structurally deficient — the FHWA classification for any span where deck, superstructure, or substructure carries a condition rating of 4 or below. Lower percentages indicate stronger maintenance funding and inspection follow-through. States here sit immediately above and below Missouri on the same metric.
