Sahara Avenue begins in the western valley at Red Rock Ranch Road as the continuation of Desert Foothills Drive west of the Las Vegas Beltway.

From there, the route continued due east to cross Interstate 15 and Las Vegas Boulevard.

The road was originally called San Francisco Avenue and served as the southern city limit for Las Vegas.

The Nevada Department of Transportation (NDOT) removed SR 589 from its maintenance logs by the beginning of 2019,[2] and has begun the process of turning ownership of the roadway over to the City of Las Vegas and Clark County.

Current RTC Route Sahara Avenue Express (SX) operated on this road.
