This $2.5 billion interstate highway would run within 50 miles of an existing, high-capacity U.S. highway. If completed, I-73 will be the most expensive transportation project in South Carolina’s history, even though early reports estimate it will only shorten current travel times to the Myrtle Beach region by 15 minutes or less. Upgrading the parallel highway nearby would meet every goal outlined by the interstate’s proponents, and cost only $150 million. Though the state authorities have yet to identify funding sources for the project, federal taxpayers could be expected to cover 80 percent of the costs ($2 billion) in addition to the $100 million the federal government has already designated for the highway. The project is divided into two corridors, the North Corridor estimated to cost $1.25 billion and the South Corridor estimated to cost $1.29 billion.
