The South Carolina State Highway System is the fourth largest state-maintained system of state highways in the country. It consists of Interstates, U.S. highways, state highways, and secondary roads, totaling approximately . South Carolina uses a wide shield for all routes, regardless of number of digits.

Secondary roads

South Carolina utilizes a numbering system to keep track of all non-interstate and primary highways that are maintained by SCDOT. First appearing in 1947 (when a huge amount of highways were cancelled or truncated), the "state highway secondary system" carries the number of the county followed by a unique number for the particular road. An example is S-11-154, which defines a secondary road in Cherokee County (11) with a road number of 154 (Whelchel Road). The counties are numbered in alphabetical order, with Abbeville as 1 and York as 46. Secondary road signs may either be integrated with a street name sign or appear separate as a black rectangle with white lettering.
