Update: All traffic is clear and moving again.
Original: Drivers in Spartanburg County will have to deal with slow traffic for most of Thursday on Southbound Interstate 85 near Wellford.
The S.C. Department of Transportation tells our Emily Henning crews are working on potholes that developed from the weather system that moved through on Wednesday.
The work is being done on Southbound I-85 about a mile from Exit 68 which is the interchange for Highway 129.
The two right lanes are closed and traffic is moving slowly through the area. Traffic has been backed up at least two miles as a result.
SCDOT crews say it will take much of the day to complete the work.
