South Carolina has many numbered highways maintained by the state. These roads fall into one of three categories: Interstate highways, U.S. highways, and state highways. Most numbered highways in the state are maintained by the South Carolina Department of Transportation.
The old SC Highway shield design.
In 2007, the Legislature allowed the signs marking the primary state highways to be changed from the old black-and-white to the new blue-and-white design, which features an outline of the state, the Palmetto Tree & Crescent symbol from the state flag, and the words "SOUTH CAROLINA" spelled out along on the top of the highway shield. South Carolina uses a wide shield for all routes, the width most states use only for three-digit routes. The former shield was a simple white rectangle with a black border, with the letters "S.C." on top.
