SC 640  not currently assigned
Previous SC 640's:		SC 640: Appeared in 1939 as new primary routing. Ran from SC 64 (current US 17 ALT) east of Walterboro northeast to SC 65 (current SC 61) near the Koger Tomb. In 1941 or 1942, SC 640 was extended north across the Edisto River to end at SC 173 (current S-18-30). In 1948, all 15 miles of SC 640 were downgraded to S-15-21 and S-18-29.

From: Allendale (Allendale County) To: near Lodge (Colleton County) Total Length: 21.4 miles
ROUTE LOG US 301: 0 - 0 US 321: 4.2 - 4.2 Bamberg-Allendale Line: 7.6 - 11.8 Colleton-Bamberg Line: 2.2 - 14 US 601: 1.4 - 15.4 SC 64: 6 - 21.4		Creation: Appeared in 1931 or 1932 as new routing. Only ran from SC 64 west to SC 36 (current US 601) Adjustments: In 1937 or 1938, SC 641 was extended west as new routing to SC 33-331 (current US 321) Sycamore. In 1942, SC 641 was given a straighter alignment between Sycamore and Colleton County, leaving behind a secondary road (S-5-8 today) and SC 330 (S-5-31 and S-15-37 today). Note that the Sycamore to SC 36 (current US 601) distance has dropped from 13 to 11. In 1947 or 1948, SC 641 was extended west to Allendale, replacing a piece of SC 73. SC 641 was extended further west to the south boundary of the Savannah River Plant (replacing part of SC 28) in 1953. This made SC 641 44 miles long. SC 641 west was truncated back to US 301 between 1968-70, replaced by SC 125. Between 1948-70 it may not have been possible to travel through the Savannah River Plant. Improvements: Fully paved on the 1932 map; Extensions weren't paved until 1942. No multilane sections. Comment: SC 641 makes an empty but fine short cut to travel from Augusta to Charleston via SC 125-641-64....

In 1948, SC 642 was placed on the entirety of Dorchester Rd. below SC 61 (current SC 165) The route to Knightsville, Jedburg, and Pinopolis became S-18-22 and S-8-16. The piece between SC 61 and today's S-18-22 was still part of SC 65. SC 642 ws extended over SC 65 back out to US 17 ALT in 1951 or 1952. Improvements: SC 642's current alignment was shown as mostly not paved up through 1953. SC 642 was 4-laned out to Ashley Phosphate Rd. (S-18-62) by the mid-70's. This 4-laning was extended out to Oakbrook (S-18-199) in the early 1990's. Comment: SC 642 serves the Charleston AFB.
