state highway in Clark County, Nevada, United States
State Route 159 (SR 159) is a 19.180-mile (30.867 km) east–west highway in Clark County, Nevada, United States, providing access to Red Rock Canyon and formerly serving as a thoroughfare in the Las Vegas Valley. A portion of the west end of the route is designated a Nevada Scenic Byway.
Route description
SR 159 has two distinct segments. The first segment is a rural two-lane highway that begins at its junction with SR 160 (Pahrump Valley Highway, Blue Diamond Road) and Erskine Junction Way. From here, two things happen. First, the designation Blue Diamond Road continues onto SR 159. Second, the highway proceeds northwesterly through the town of Blue Diamond toward Spring Mountain Ranch State Park. The last signs for Blue Diamond Road can be found at an at-grade intersection with Castalia Street. After this intersection, SR 159 is officially known as Red Rock Canyon Road, despite the name being completely unsigned. From there, the highway curves northeastward around Red Rock Canyon to the Las Vegas city limits west of the Las Vegas Beltway.

Why this record matters
“Nevada State Route 159” is worth following because a concise public description often conceals a longer documentary argument. Here, Nevada, State and Route provides the most credible route into that argument.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 17, 2026. The linked authority identifier is Q886745. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
