Structure 21144 · Jefferson County, AL
Carries 11th AVE Ramp I-65 over I-65 I-20 I-59, I-20 59 65.
Set by its lowest-rated component: Deck and Superstructure at 7 of 9.
How ratings work5,408 ft end to end, longest span 260 ft: about 15 football fields, or 1.0 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 multi-beam 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.
