Total Length: 14 miles  
ROUTE LOG
SC 5 Bus: 0 - 0
SC 322: 9 - 9
SC 72, SC 121: 5 - 14
Creation: Created in 1948 mostly as new routing. Originally ran US 321-SC 5 York northwest to SC 55 near Kings Creek. The westernmost 3 miles had been SC 556 prior to 1948. This is the 2nd SC 324.
Adjustments: In 1950, SC 322 was extended east to its current ending at SC 72 as new routing, although some of this had been part of the 1st SC 324. This gave SC 324 its maximum length of 27 miles.
In 1951 or 1952, SC 324 west was truncated to its current end in eastern York, replaced by a rerouted SC 5 (which used to go through Sharon and Hickory Grove on its way to Kings Creek).
Improvements: SC 324 was fully paved upon creation; no multilane segments
Comment: SC 324 #1 and #2 may have been one and the same, but two different 1946 maps show York to SC 55 as unnumbered...
Previous SC 324's: SC 324 #1: Appeared in 1940 as new primary routing. Ran from SC 322 east to US 21 (current SC 72-121) near Ogden.
SC 324 (1940 official)
In 1941 or 1942, SC 324 was extended west to US 321 Delphia. Also, a discontinuous segment of SC 324 appeared as a short stub off SC 5 east of York (today's SC 324's endpoint).
SC 324 (1942)
In 1948 the 11 miles of continuous SC 324 were downgraded to S-46-32, and the discontinuous piece was downgraded as well. Today, the stub piece is connected to the original piece, and has been numbered as SC 324 since 1950.

Total Length: 22.6 miles  
ROUTE LOG
US 52, US 301: 0 - 0

SC 327 (1942)
Adjustments: In 1947 or 1948, SC 327 was extended east as new routing to end at US 76-301 Winona (just west of the Great Pee Dee River).
SC 327 was rerouted to run from Claussen to US 76-301 Mars Bluff in 1957 or 1958. The old way to US 76-301 became some of S-21-13 and S-21-24.
SC 327 was extended to I-95 in 1971 or 1972 replacing parts of S-21-64.
SC 327 was rerouted slightly to avoid the lumber mill near Claussen in the early 90's.
When I drove down I-95 in January 2005, SC 327 was posted to continue north, to where I do not know.
Improvements: Paved from Effingham to Evergreen in 1951 or 1952; Evergreen to Clausen was paved in 1953; SC 327 was fully paved in 1957 or 1958.
SC 327 was multilaned on its US 76-301 multiplex when extended in 1971-72. The piece around Francis Marion College has been 4-laned for a long time, as well. The section from Mars Hill to I-95 was 4-laned in 1992.
Comment: SC 327 serves as the main way to get from I-95 to US 76 for the ride to Myrtle Beach. SC 327 did not used to touch US 301 in Effingham, but US 301 was realigned to make the connection in the late 90's.
SC 328  not currently assigned
Previous SC 328's: SC 328: Appeared in 1941 or 1942 as new primary routing. Ran from US 321 York south for 6 miles.

Creation: Created between 1980-82 as an upgrade to S-11-32. Ran as it does today. The northernmost 2 miles had been SC 180 prior to 1948. This is the 2nd SC 329.
Adjustments: None
Improvements: SC 329 was fully paved upon creation; no multilane segments
Comment: SC 329 serves as an eastern bypass for Gaffney, although hardly anyone probably needs to go from SC 105 north to SC 18....
