Hall thanked Gov. Henry McMaster and the transportation commission for the opportunity to continue to lead the agency.

“I also want to thank the South Carolina General Assembly for recognizing the need to boost funding for infrastructure and to continuously evaluate those funding levels in order to keep pace with rapidly evolving business, residential and economic development needs,” Hall said.

Hall oversaw the agency as restored its finances and financial reputation, developed and carried out a strategic 10-year plan, and accelerated critical interstate widening projects.
