The highway makes a quick turn towards downtown Sandersville as SR 242 Spur continues straight.

Farther to the southeast, it crosses a Central of Georgia Railway line.

After leaving town, SR 242 continues to the southeast, and gradually curves to the east and enters Jefferson County.

It continues to the east to meet its eastern terminus, an intersection U.S. Route 221 (US 221)/US 319/SR 78/SR 171 in Bartow.

It travels through a forested area and intersecting no paved roads until it curves to the north-northwest to its northern terminus, an intersection with the SR 242 mainline (West Church Street), only one-tenth mile (0.16 km) from the latter's western terminus at SR 24.
