About 15 miles of I-385 is scheduled to be closed for eight months for repairs beginning Jan. 4.
Motorists who want to stay on interstates from Columbia to Greenville should stay on I-26 to Spartanburg, then drive southwest on I-85.
A local detour involves Interstate 26 to S.C. 92, then back to I-385 near Gray Court. That adds eight miles and 15 minutes to a trip.
Another alternative is U.S. 76 though Laurens to S.C. 14, back to I-385. That adds four miles but is more congested and also adds about 15 minutes.
