Previously, Roberts served 12 years in the state House of Representatives. Among other things, the Ocilla Republican chaired the transportation committee, where he helped pass 2015 legislation that raised a billion extra dollars a year for road and bridge construction.
Then-Gov. Nathan Deal appointed Roberts to the GDOT planning director’s job that same year. In that role, he served as the governor’s point man at the agency and helped develop long-term road construction plans.
