State senators unanimously approved Christy Hall as head of the S.C. Department of Transportation on Thursday.
Gov. Nikki Haley appointed Hall as acting secretary after former secretary Janet Oakley resigned in June.
Haley nominated Hall to officially lead the agency in October.
Hall, 44, has worked at the Transportation Department for more than 20 years.
She led the agency through October’s historic flooding, which closed 541 roads and bridges at its peak.
