North of this junction, Highway 138 passes two cemeteries, including the nearby Taylor Log House and Site.

[3] The route next enters Desha County, serving as the southern terminus of Highway 159.

The road is a two-lane, undivided, rural route for its entire length.

This change is still apparent on the highway map, as Highway 4 was later replaced by US 278, which creates today's "kink" in US 278 in east Drew County.
