SH-67 begins at the main entrance of the Mountain Home Air Force Base, located in southwestern Elmore County.

From the junction, SH-67 turns northeast and travels through a section of the Morley Nelson Snake River Birds of Prey National Conservation Area in the barren outskirts of Mountain Home as a four-lane, undivided highway.

The history of SH-67 goes back to at least the 1930s, when the first all-weather gravel road connecting Grand View and Mountain Home was built (represented by today's SH-167, SH-67 and SH-51), and can be seen on a 1937 map of the area.

The route received its current number designation in the late 1960s in honor of the base's then-host unit, the 67th Tactical Reconnaissance Wing (1965-1971).

The original SH-67 also included the entirety of SH-167 from Grand View to where it currently intersects with SH-67 approximately 1.5 miles (2.4 km) from the base's main gate.
