State Route 24 (SR 24) is a state highway in the south-central region of Washington, in the United States. It travels from Yakima to Othello, across a portion of the Columbia Plateau. The highway crosses the Columbia River on the Vernita Bridge, located near the Hanford Site. SR 24 terminates to the west at an interchange with Interstate 82 (I-82) in Yakima and to the east at SR 26 in Othello. The highway was added to the state highway system in 1937 as Secondary State Highway 11A (SSH 11A), composed of several county-built gravel roads from Yakima to Connell, with a ferry crossing at Hanford. The Hanford section of SSH 11A was closed in 1943 due to wartime activities at the Hanford Nuclear Reservation, forcing the state government to relocate the highway to the north side of the Columbia River. The new highway opened in 1961 and was supplanted by the new Vernita toll bridge in 1965. During the 1964 state highway renumbering, SR 24 replaced most of SSH 11A and was rerouted to a terminus in Othello. Route description SR 24 begins in eastern Yakima as an extension of Nob Hill Boulevard at a diamond interchange with I-82 and the concurrent US 12 and US 97. The interchange is located southeast of the Central Washington State Fairgrounds and the SunDome arena. SR 24 travels southeasterly from the interchange as a four-lane divided highway and crosses the Yakima River into unincorporated Yakima County near Yakima Sportsman State Park. The highway narrows to two lanes and continues southeast along the Central Washington Railroad, a branch of the BNSF Railway, changing course to bypass the city of Moxee on its south side. SR 24 continues beyond the railroad's terminus and runs deeper into the Moxee Valley, an irrigated area situated between the Yakima Ridge and Yakima Training Center to the north and the Rattlesnake Hills to the south. At the east end of the valley, SR 24 turns northeast and crosses through a narrow pass in the hills before reaching the Black Rock Valley, which it continues across. Midway through the valley at the Silver Dollar Cafe, the highway intersects SR 241, an auxiliary route that travels south towards Sunnyside. SR 24 continues northeast from the junction and enters Benton County, where it climbs a section of the Yakima Ridge and exits the valley. The highway crosses part of the Fitzner–Eberhardt Arid
