State Route 68 (SR 68) is an 18.7-mile-long (30.1 km) state highway that travels south-to-north, in the shape of the letter L, through portions of Washington County in the east-central part of the U.S. state of Georgia.

Then, it continues northeast until it enters Tenille.

At the northern end of the concurrency, SR 68 turns to the northwest until it meets its northern terminus, an intersection with SR 24/SR 540 (Fall Line Freeway) just west of Sandersville.

Here, the roadway continues as SR 24 Spur (Yank Brown Road).

[1] The entire route is in Washington County.
