There are over 41,000 miles of roadways and 8,442 bridges that make up our state highway system. This extensive transportation network connects South Carolinians to all aspects of their everyday life – including education, employment, social services, health care, consumer services, and retailers.
Our roads and bridges also serve South Carolina’s manufacturing, agricultural, and commercial industries who utilize the transportation network for commerce and need to move freight in a timely and efficient manner.
Drivers travel over 60 billion miles annually in South Carolina. The majority of traffic occurs on a quarter of our state system, specifically on interstates and primary routes. In contrast, half of the state system carries approximately 6% of traffic.
In order to repair, maintain, and improve this extensive network, South Carolina depends on federal dollars and state revenues derived from fuel taxes and other driver/vehicle related fees. Learn more about those funding sources here.
