On this week's episode of Tying it Together, host Tim Boyum tackles one of the biggest and most talked about issues in North Carolina — traffic.

As a growing state, we are seeing all kinds of improved roads and many new designs, including roundabouts, diamond interchanges, and beyond.

N.C. State is a hotbed for a lot of the research that goes into these decisions. This week, Dr. Daniel Findley, Associate Director for the Institute of Transportation Research and Education at N.C. State, joins Tim to discuss those issues plus another enormous challenge surrounding the gas tax and funding roads.
