North Carolina’s DOT spent less than predicted in the second half of 2020, a state performance audit showed. But the report’s authors said the agency hadn’t carried out key recommendations from an audit last year that found several hundred million dollars in overspending. The audit, announced yesterday by State Auditor Beth Wood, showed that the DOT spent $2.52 billion for the six months ending last December 31st, or $325 million less than its baseline spending forecast.
