Swansea, SC 08/02/2026 - The South Carolina Department of Transportation (SCDOT) will temporarily close the Interstate 26 eastbound Exit 129 ramp to Highway 21 as part of a new ramp alignment project beginning Friday, August 7.

Weather permitting, the ramp closure will begin at 8 p.m. on Friday and remain in place until 6 a.m. on Tuesday, August 10.
