With a growing population and skyrocketing construction costs, the N.C. Department of Transportation needs more help to build and improve roads and infrastructure across the state.

If you’re driving around a high-growth area of the state, there’s a decent chance you might be stuck in traffic – and those daily bottlenecks are only getting worse. The Department of Transportation knows exactly where it needs to widen roads and build new ones to ease that congestion. But with inadequate revenue from the gas tax, construction on those improvements could be years away. DOT has a list of $144 billion in transportation infrastructure projects submitted by local leaders, but it only has $5 billion to spend 

WUNC News sat down with NCDOT Secretary Daniel Johnson at the agency’s Raleigh headquarters to get a better picture of the state’s transportation funding challenges, from controversial toll roads to the shifting sands around N.C. 12 on the Outer Banks.
