Structure 900094 · Monroe County, FL
Carries US 1 (sr 5) over Long Key Channel, Long Key (mm 63.2).
Set by its lowest-rated component: Superstructure and Substructure at 5 of 9.
How ratings work12,176 ft end to end, longest span 118 ft: about 34 football fields, or 2.3 miles. Lengths are drawn to scale; at this length a semi-truck would be a speck. Each part is colored by its latest inspection rating. The inventory records lengths but not heights or the layout of the shorter spans, so those are drawn as typical for a segmental box-girder bridge.

Inspectors rate each major part of a bridge (the deck you drive on, the superstructure of beams that holds it up, and the substructure of piers and abutments beneath) on a 0–9 scale. A bridge's overall condition is its lowest of those ratings, so one deteriorated component makes the whole bridge "poor."
A poor rating is not a closure. It means the bridge is flagged for priority repair or replacement; bridges judged unsafe are closed or posted with weight limits. The waterway (channel) rating is reported, but it does not count toward the overall classification.
