SC 132 #1: Appeared in Feb 1937 (SCDOT) as new primary routing, running from SC 13 (now SC 124) Greenville north 0.2 miles. In May 1937 (SCDOT), SC 132 was extended as new BELT routing northeast to US 25 ALT (now S-23-13/1180 jct). In 1947, SC 132 was downgraded to S-23-20 Lois/Woodside Aves and S-23-19 (now SC 183 Cedar lane Rd and S-23-1180 Buncombe Rd. SC 132 #2: Appeared in 1974 or 1975 as a renumbering of US 321 CONN on Dawson Dr from US 321 to US 321 Bus northwest of Chester, then around the north of Chester as new primary routing to end at SC 72-121. Between 1981-87, SC 132 was renumbered as SC 97 from US 321 Bus east to SC 72-121 and P-1203 west of US 321 Bus (now S-12-383). This is the only instance I know of where a signed state route was downgraded to a P-xx route.
