Intersection Overview
The Spring Mountain Road approach to the I-15 South on-ramp is where Strip-area traffic transitions to the freeway heading south — toward the airport, Henderson, and the south valley. Spring Mountain compresses multiple lanes of mixed local and tourist traffic into the ramp merge zone, with casino properties, the Palms, and residential areas generating a diverse traffic mix with widely varying driver familiarity with the interchange geometry.
Notable Statistics & Trends
Zero fatalities across all three years. The injury count (69) relative to crash count (87) is notably high — averaging nearly 0.8 injuries per crash — suggesting crashes frequently involve multiple occupants. The crash count dropped sharply from 43 in 2022 to 18 in 2023, then partially rebounded to 26 in 2024. The partial rebound suggests the underlying conditions weren’t fully resolved by whatever changed in 2023.
