SC 430
From: SC 23 Edgefield (Edgefield County)
To: US 378 (Edgefield County)
Total Length: 12 miles  
ROUTE LOG
SC 23: 0 - 0
US 25: 2.4 - 2.4
US 378: 9.6 - 12
Creation: Appeared as new state routing in 1939. Originally ran from SC 43 (current US 378) south to US 25 north of Edgefield.
Adjustments: In 1940, SC 430 was extended in both directions: north to the Saluda County Line and south through Edgefield to a point 4 miles south.
In 1941 or 1942, SC 430 was extended in both directions again: north to SC 241 (current S-24-30) and south all the way to US 25 near today's I-20 interchange. This brought SC 430 to a length of 34 miles in 4 counties.
In 1948, SC 430 was changed to today's routing, leaving behind S-2-36, S-19-34, S-19-24, S-40-38, and S-24-62. The piece from US 25 to SC 23 is shown as a primary route on the 1942 Official Map, but does not indicate its number.
Improvements: SC 430's current routing was paved in 1941 or 1942; no multilane sections
Comment: The US 25 to SC 23 piece may have been briefly posted as SC 430 ALT in the 1980's, but I have no maps currently that show this.
