List of Numbered Highways in South Carolina - Signage

Signage

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.
