SR 240 is maintained by the Washington State Department of Transportation (WSDOT), which conducts an annual survey on the state's highways to measure traffic volume in terms of average annual daily traffic. The busiest section of the highway, across the Yakima River Delta south of I-182, carried a daily average of 76,000 vehicles in 2016; the least busiest section of the highway, near its intersection with SR 24, carried only 2,600 vehicles. The Bypass Highway section of SR 240 in Richland is designated as part of the National Highway System, a network of roads identified as important to the national economy, defense, and mobility. The corridor, along with the freeway section from Richland to Kennewick, was also designated as a Highway of Statewide Significance by the Washington State Legislature.
