State Route 24 (SR 24) is a 79.23-mile (127.51 km) long state highway in the U.S. state of Washington. Beginning at an interchange with Interstate 82 (I-82) in Yakima, the highway travels east into the Yakima highlands before turning north at the Hanford Site to cross the Columbia River on the Vernita Bridge. From the crossing, the highway travels east through the Hanford Reach National Monument and turns north to end at SR 26 in Othello. The highway was known as Secondary State Highway 11A (SSH 11A) from 1937 to 1964 and was originally routed through the Hanford Site until the 1940s. The Vernita Bridge was completed in 1965 along with the route to Othello north of the Hanford Reach and paved in the 1970s.
State Route 24 (SR 24) begins as Nob Hill Boulevard at a diamond interchange with Interstate 82 (I-82), concurrent with U.S. Route 12 (US 12) and U.S. Route 97 (US 97), in Yakima. The highway turns southeast to cross the Yakima River and travelling into unincorporated Yakima County, parallel to a short BNSF Railway line. SR 24 continues into Moxee, where the rail line ends, and turns east into Black Rock Valley, situated between the Yakima Ridge to the north and the Rattlesnake Hills to the south. The roadway forms the northern terminus of SR 241, a highway that travels south to Sunnyside, before entering Benton County and the Hanford Reach National Monument. At the western boundary of the Hanford Site, SR 24 turns north at the northern terminus of SR 240, which travels south to Richland. The highway passes a rest area and crosses the Columbia River on the Vernita Bridge into Grant County, turning east at the southern terminus of SR 243. The roadway travels east through the Saddle Mountain National Wildlife Refuge and passes Saddle Mountain Lake before entering Adams County. SR 24 turns north and becomes Broadway Avenue in Othello, where the route ends at an intersection with SR 26.
