Also in 1925 or 1926, SC 9 west was rerouted at Kelly to instead head west as mostly new primary routing through Jonesville to end at SC 19 (now SC 56) Spartanburg. The old routing southwest through Union to Enoree became SC 92. Today this is Waterside Park Dr and Rock St in Enoree; SC 92 to Cross Anchor except: S-42-256 Ice House Rd; S-42-10; New Hope Church Rd. It is SC 49 from Cross Anchor to Union except: Red Barn Rd and Compton Cirle west of Cross Keys; S-44-18 and S-44-22 through the Cross Keys crossroads; unclear if SC 9 used Boatman Springs Rd east of the Tyger River. At Union SC 9 used S-44-6 Main St; SC 18; S-44-48 Pinckney St; SC 49 Arthur Blvd; S-44-122 Calhoun St; S-44-383 Lakeside Dr; S-44-69 Peach Orchard Dr; S-44-382 Barnado Rd; S-44-4 to Kelly.
Also in 1925 or 1926, SC 9 was rerouted between Lancaster and Pageland to follow a southern arc. The original path was secondary for a while but is now again the SC 9 corridor.
If SC 9 ever used the length S-42-240 and S-42-227 Main St through Pacolet along with S-42-108 Elmore Rd it stopped doing so by 1927.
In 1932, SC 9 east was truncated to SC 49 (now S-26-20) Nixons Crossroads. The road through Little River to NC became part of SC 49 (now SC 90 and US 17).
In 1932, SC 9 was removed from SC 909/S-12-41 and S-12-559 in the Rodman area.
SC 9 was removed from S-29-57 Old Landsford Rd/York St by 1932.
If SC 9 ever used Bascus St/Scott St south out of Lake View; Currie Rd at the Dillon-Marlboro Line it stopped doing so by 1932.
If SC 9 ever used Cobblestone Rd south of Green Sea it stopped doing so by 1934.
In 1934 or 1935, SC 9 east was rerouted at Loris to head directly as new primary routing to US 17 Nixons Crossroads. Loris to Wampee is probably S-26-348, S-26-347, and S-26-638 which used the now abandoned Star Bluff Ferry. Wampee to Nixons Crossroads became an extended SC 90.
Also in 1934 or 1935, SC 9 was extended with US 176 through Spartanburg, then replaced SC 177 north through Boiling Springs and New Prospect to North Carolina.

Also in 1934 or 1935 it appears SC 9 was removed from today's S-35-36 between Kollock and Bennettsville. In the process, SC 9 was placed on new construction then replaced SC 98 southwest to the old routing.
Also in 1934 or 1935, SC 9 was removed from John Price Rd and Sand Castle Rd east of Pageland; S-13-39 southwest of Pageland.
In 1936 or 1937, SC 9 was removed from Old Loris-Longs Rd east of Loris.
In 1939, SC 9 was rerouted in Cheraw and eastward to meet the new Pee Dee River bridge that SC 9 still uses today. The old route may have briefly been SC 9 ALT. Today it is 2nd St and Church St and on the other side of the river it is S-35-52.

Between 1939-43, SC 9 was removed from Peach Shed Rd east of Jonesville.
About 1946, SC 9 was moved onto Pine St entering Spartanburg as new primary routing and construction, then used US 29 Main St back to Church St. US 176 remained on Church St. The old route between SC 9 and then-US 176 became SC 9 ALT but it is today S-42-34, SC 295 and SC 56.

In 1949, SC 9 was given its bypass south of Chesterfield over what had been SC 100 prior to 1947. The old route through Chesterfield became SC 9 Business (now S-13-1). Official maps showed the bypass as well as the 1949 Official having a SC 9 BUSINESS graphic on the reverse, however county maps didn't explicitly label it until the 1960s.

There is a posted SC 9 TRUCK for Cheraw using US 52 and S-13-51 Four Mile Loop.
I used to think SC 9 from Cheraw east to the beach should be part of an extended US 220 but with I-73 overrunning US 220 in North Carolina it would actually make more sense to eliminate US 220. A US x74 would make some sense for SC 9 from Spartanburg to the beach but it would have to either also use SC 9 into NC or be put onto I-26 to comply with the rules for US route designations...
