South Dakota Highway 26 is a state route that runs across central and northeast South Dakota. It begins at a junction with South Dakota Highway 47 north of Highmnore, and terminates at U.S. Highway 281 just south of Redfield. It is 50 miles (80 kilometers) in length. The current alignment is the second use of the SD 26 identifier. The original SD 26 was implemented in the late 1920s. It began at South Dakota Highway 25 west of Bryant, and ran east to U.S. Highway 77 near Estelline. This route was redesignated as South Dakota Highway 28 around 1934.
