Does anyone really know if tolls are helping with NC metro congestion?

North Carolina, like many other states, has gambled on toll roads as a way to reduce congestion.

While a relatively recent addition to the state’s highways, some estimates say toll roads in the Triangle and Charlotte areas are drawing more drivers than officials initially predicted.

So, how are the toll roads doing at what they were supposed to accomplish — reducing congestion?

A Carolina Public Press investigation found that the state appears to lack clear answers and to be in no hurry to find out whether the wealth, materials, acreage, sweat and frustration sacrificed to create the new toll routes have been justified in each case or in any case.
