| Good condition | 3,455 (36.4%) |
| Fair condition | 5,326 (56.0%) |

South Carolina ranks 20 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.
With a poor share close to the national rate, expect a steady mix of replacement, rehabilitation and preservation work. Fair-rated bridges (5,326 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.
