Bridges
| Bridges in the National Bridge Inventory | 8,590 |
|---|---|
| Good condition | 5,378 (62.6%) |
| Fair condition | 3,120 (36.3%) |
| Poor condition | 92 (1.1%) |
| Total deck area | 67,121,374 sq ft |
| Deck area in poor condition | 539,138 sq ft (0.8%) |
Arizona ranks 50 of 51 (states plus DC) for the share of bridges in poor condition, where 1 is the highest share. Nationally, 6.6% of bridges are rated poor.
A poor share near or below the national rate usually shifts the work toward preservation, inspection and load rating rather than full replacements. Fair-rated bridges (3,120 here) are the ones most likely to slip to poor without timely work, which is why many DOTs fund preservation and inspection contracts alongside replacements.
