Two discontinuous segments of the road totaling 8.487 miles (13.659 km) are designated State Route 592 (SR 592).

The second section resumes at Paradise Road and continues east, skirting the northern edge of the University of Nevada, Las Vegas (UNLV) campus before reaching its terminus at Boulder Highway (SR 582).

In the early 1980s, the Nevada Department of Transportation rebuilt the Dunes interchange at I-15, and constructed a six-lane Flamingo Road west to Rainbow Boulevard.

The segment between I-15 and Las Vegas Boulevard remained named Dunes-Flamingo Road until 1995.

The route is a candidate to be decommissioned with control given to Clark County; however, only the above section located in the resort corridor has been relinquished as of January 2008.
