A few days ago we were treated to reports of a new I-73 study by Parsons Brinckerhoff commissioned by the Grand Strand Business Alliance.

Local media reported that the new study found two previous studies commissioned by the Coastal Conservation League, advocating an upgraded expressway link to I-95, not credible. It further reported two previous studies completed by the Northeast Strategic Alliance and Dr. Don Schunk of CCU, advocating for construction of I-73, were credible.

Not really. The Parsons Brinckerhoff study questioned the cost of the CCL study as being too low, said a four-lane upgraded expressway would not be comparable in capacity to a six-lane interstate and performed some literary gymnastics with benefit-cost analyses and economic development benefits for the differing studies.
