Columbia, S.C. (WOLO)– Officials with the SC Dept. of Transportation say drivers can expect overnight closures of ramps on I-126 and Colonial Life Blvd. A spokesperson for the agency says drivers will instead be detoured to the Greystone Blvd./Riverbanks Zoo exchange. Signs will be posted to show drivers where to go. The detours will start Sunday night at 9pm and end Monday morning at 5am. Officials say the detours will allow crews to complete the retaining wall currently under construction as part of the Carolina Crossroads project.       Categories: Lexington, Local News, News, Richland
