State Highway 120, also abbreviated as SH-120 or OK-120, is a 3.04-mile-long (4.89 km) highway in the eastern part of the state of Oklahoma, USA.[1] It connects SH-112 between Pocola and Cameron to the Arkansas state line. The highway runs through the town of Rock Island and Le Flore County for its entire length.

After crossing the state line, it becomes Highway 10, which runs to Little Rock.

Route description[edit]

Highway 120 begins at SH-112 and heads due east. It indirectly serves the core of Rock Island, passing to its north. 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.[2] The highway then ends at the Arkansas state line, west of Hackett, Arkansas.


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.[3] The road was paved in 1968.[4] The road has always had the same general route.
