Blue Diamond Rd (NB)

Blue Diamond Road — SR-160 — is the primary route from the southwest Las Vegas Valley toward Pahrump and the rural Nevada communities beyond. For locals it’s the road to Red Rock Canyon’s southern entrance, to Bonnie Springs, and to the Mountain Springs area. It transitions from a multi-lane divided road at its eastern end near the 215 to a two-lane desert highway further west. The crash data covers the northbound direction through the Las Vegas Valley section, serving both local residential traffic and recreational drivers heading to outdoor destinations.

The improvement on Blue Diamond Road is among the most dramatic in the dataset: 332 crashes in 2022, 258 in 2023, 132 in 2024 — a 60% reduction in two years. Zero fatalities in 2024. The alcohol rate of 7.2% across three years is elevated, likely reflecting recreational use patterns — drivers returning from outdoor activities or from Pahrump casinos. The dramatic improvement may reflect speed enforcement, road improvements, or changed routing patterns as nearby construction altered travel choices.
