Its northern terminus was at SR 38 in the downtown of the Fayette County village.

Designated in the mid-1920s and located in the northeastern quadrant of Fayette County, SR 238 essentially served as a spur route between the US 62/SR 3 concurrency and SR 38, as the two routes ran generally parallel with one another at a separation of about 1 mile (1.6 km) for a distance of approximately 3.5 miles (5.6 km) between Washington Court House and Bloomingburg.

Heading northwest from there, the two-lane state highway traveled amidst a vastness of farmland, while passing by a couple of homes along the way.

With the Bloomingburg Cemetery abutting the west side of the highway, SR 238, which is now known as Main Street, passed a business and some residences prior to coming to an end at its junction with SR 38 at a four-way stop intersection in the village's downtown area.

The highway did not experience any significant changes between its designation and decommissioning between 2014 and 2015, when it was replaced by a rerouted SR 38.
