State Route 224 (SR 224) is a 10.15-mile (16.33 km) long state highway located entirely in Benton County, Washington, United States. The highway serves to connect SR 225 to Interstate 82 (I-82) and U.S. Route 12 (US 12), and to link Benton City to West Richland and Richland. Before the 1964 state highway renumbering the highway was numbered Secondary State Highway 3R. SR 224 is a lightly traveled rural highway except through Richland, where an average of 16,000 cars traveled the highway daily in 2009. The Washington State Department of Transportation (WSDOT) rebuilt its southern terminus as a roundabout in 2016, as part of a project to improve traffic congestion near the Red Mountain AVA.
