The original Highway 143 was created in 1931 from Highway 18 in Black Oak south to US 63 southeast of Tyronza Township.[4] This route became part of Highway 135 in 1955. The current Highway 143 was created by the Arkansas State Highway Commission on June 23, 1965.[1] The route was paved from US 62 to Grandview in 1974, with the remainder being bituminous surface/gravel.[5] The entire routing was paved by 1988.[2]
