Not sure if these GMaps links carry over the time capsule settings so some adjustments and clicking around may be required.
Using the "time capsule" feature (if you click the clock icon on applicable roads, you can see previous/old Street View images) available in desktop GSV I'm able to bring up a May 2008 snapshot of Georgia 24/540 being a two-lane road, prior to 4-laning on both sides of this area. West side of the area in question. It seems to follow the current route, though is missing coverage on both ends where the road divides.

Curiously the footage seems to have been taken earlier this year, yet stops as soon as you get to the old/incomplete/??? section of road. The road loses its paved status before it terminates at somebody's house.

Looking at more 2008 GSV (on 24/540) it seemed that this was part of Brooks Road, but in current GSV there's a new sign naming this unpaved road as "Skyview Drive".

"Access to 7574 Hwy 24 W". The duplicate sign may or may not be a GSV graphical glitch, I'm not sure.

Addendum:
http://www.dot.ga.gov/applications/geopi/Pages/Dashboard.aspx?ProjectID=0015878http://www.dot.ga.gov/applications/geopi/Pages/Dashboard.aspx?ProjectID=0016829Found these two projects listed on the GDOT website - the first seems to be regarding widening this section of 24/540 to a 4-lane road, though following the
existing alignment.
The second one is some sort of "scoping" project from 2019, listed under the name "FALL LINE FREEWAY FM SR 24 TO BROOKS RD-GEOTECHNICAL SCOPING".
(There's no corresponding project for the western section, or at least there isn't one shown on the GDOT project lookup interface.)
Addendum 2:
Listed on the first GDOT project link were a few PDFs that I didn't look at before - right at the first page of information from the CR (Concept Report) JUN2019 PDF:
PLANNING AND BACKGROUND
Project Justification Statement: Project number 0015878 is just west of the City of Sandersville in Washington
County. This new project was programmed at the request of the Office of Roadway Design in November 2017.
This section of SR 24 was identified for improvement as a result of catastrophic soil failure on PI 222285, a section
of the SR 24/Fall Line Freeway from west of Indian Trail Rd to west of SR 68.
Project begins along SR 24 from east of Chambers Brooks Spring Road to west of Helton Lane. These limits were
determined to minimize the need for additional ROW and provide a safe buffer between the subsidence zone and
the main travel corridor along SR 24.
So it seems like they had to put 24 back on the old road due to a sinkhole that had formed.
