Boulder Highway was constructed in 1931, and carried SR 5 from 1932 to 1939. It later carried US 93, US 95, and US 466 from near Boulder City through Henderson and into downtown Las Vegas. The US 466 designation was later removed in 1971. During the late 1980s, the Nevada Department of Transportation (NDOT) worked to extend the US 95 (Oran K. Gragson Expressway) southeast from downtown to Henderson. As portions of the freeway opened, the US 93 and US 95 designations were gradually relocated from Fremont Street and Boulder Highway, relegating the highway to state route status. In 1995, the freeway was completed to the Wagonwheel interchange and US 93 and US 95 had been completely removed from SR 582.
