In Delight, the route begins a westbound overlap with Highway 26 for approximately 12 miles (19 km) to Murfreesboro.

The route terminates at Narrows Dam at Lake Greeson, where it continues as Beacon Hill Road.

[5] The route began where US 79 currently crosses the Louisiana state line, and ran north along present-day US 79 to Magnolia.

Upon designation, the highway continued north to Prescott via Waldo and Rosston, roughly along today's alignment of US 371 between the communities.

[8][9] Upon completion of Narrows Dam in 1951, a paved road was built to the structure from Murfreesboro, but was not initially designated a state highway.
