Columbia, S.C. (July 7, 2025) — The South Carolina Department of Transportation will temporarily close and detour the Sunny Plain Road bridge over I-26 in Calhoun County to replace the bridge beginning July 21. This replacement is part of the I-26 Widening and Improvements Project and will allow widening of the interstate to continue.
This closure is expected to last until Fall of 2026. As part of this closure, a detour route will be put in place using US 21, Caw Caw Highway and US 176. A map of the closure and detour can be found below.
SCDOT asks that drivers slow down and pay attention when driving near the work zone.
