Signage

Second shield design (1948-2006)
Variant shield design (1960s-'70s)

South Carolina Highways has had three major highway marker changes over its existence. The first signs used by the state featured an all white square with a black outline of the geographic state of South Carolina with black numbers located in the center. In 1948, a more simple design was established; still using a white square with just the numbers and the initials "S.C." at the top; a variant wider side was used for three-digit numbers. In the 1960s-1970s, an alternate was also used, which was a white square with "S. CAROLINA" partitioned at the top and number below.

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.[2] South Carolina uses a wide shield for all routes, regardless of number of digits.[3]

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 around 1950,[citation needed] the "state highway secondary system"[4] carries the number of the county followed by a unique number for the particular road. An example is S-40-33, which defines a secondary road in Richland County (40) with a road number of 33 (Gervais Street). The counties are numbered in alphabetical order, with Abbeville as 1 and York as 46.[5][6] Secondary road signs may either be integrated with a street name sign[citation needed] or appear separate as a black rectangle with white lettering.[6]
