Highway 120 begins at SH-112 and heads due east. It serves the town of Rock Island. Near its midpoint, SH-120 crosses Ivy Branch. It then has a railroad crossing. The road curves to the south as it passes through an area of sandy terrain.^[3] The highway then ends at the Arkansas state line, west of Hackett, Arkansas.^{[citation needed]}

SH-112 first appears on the 1957 state highway map, implying that it was commissioned in 1956. At that time, the entire length of the highway was gravel.^[4] The road was paved in 1968.^[5] The road has always had the same general route.^{[citation needed]}
