The eastern terminus of the route is near the junction with SR 67 at Decatur, where it continues for 2 miles as Moulton Street.

The route is one of several segments that comprises Corridor V of the Appalachian Development Highway System.

SR 24 begins at an unknown point in Decatur, possibly US 31, Grant Street, or Gordon Drive.

Past this point, the route makes a path through one of the more populated parts of Decatur as it heads towards SR 67.

In its early years (1928 - 1960), the route headed through Decatur on what is now Moulton Street, a straight road from S.R.

[2] In the early 1960s, the routing from Danville Road west was changed, heading south on Danville Road to 2nd Street before turning west, following 2nd Street to Gordon Drive, a then-new overpass thoroughfare over the railroads of Decatur; it would proceed to follow Gordon Drive to U.S.

It would follow the now extended Gordon Drive and Moulton Street over to Danville Road (where the previous routing turned south) before proceeding west.

[7] Current-Day Lawrence County Route 460 - which is located south of current-day SR-24 - held the SR-24 designation from Landersville west to Russellville as late as the mid-2000s while the four-lane divided stretch was being extended west from the stub in Landersville to another stub in western Russellville.

Abandoned and overgrown paving from the routing deviation onto now-County Road 460 is still visible on satellite and ground; although the stub is no longer existent and the divided highway is continuous.

Arguably the hilliest stretch of State Route 24, this portion of the four-lane divided highway required several ridge cuts and extensive terrain work to complete.
