South Carolina is the 11th fastest growing State in the country, outpacing the nation overall in terms of major economic indicators. Recognizing that the State's economic performance is strongly linked to its transportation network, the South Carolina Department of Transportation (SCDOT) in recent years has been faced with the challenge of how to keep pace with its transportation needs. In addition to meeting demands for new roads to serve growing areas of the State, SCDOT maintains the fourth-largest highway system in the U.S., which includes 42,000 miles of State highways and 800 miles of Interstates. Traditional highway funding sources on a pay-as-you-go basis have been insufficient to finance needed highway improvements.
