The roadway, which roughly parallels the Columbia River, begins at SR 24 southwest of Desert Aire and continues north past the Priest Rapids Dam and Wanapum Dam to SR 26 south of Vantage. The road was established originally as a branch of Secondary State Highway 7C (SSH 7C) in 1957. In 1964, the SSH 7C branch became SR 243 even though the road between SR 24 and Beverly was not complete until 1981.
