I-15 South & Sahara Ave TO I-15 South

The Sahara Avenue on-ramp to southbound I-15 is the primary freeway access point for traffic heading south from the mid-city Sahara corridor — toward the airport, Henderson, and the south valley. It serves a mix of commuter traffic, hotel delivery vehicles from north Strip properties, and visitors transitioning from the street grid to the freeway system. The ramp acceleration zone feeds into a concentrated weave zone at I-15 South.

104 crashes with zero fatalities. The count jumped from 18 in 2022 to 53 in 2023 — a nearly 200% single-year increase — before returning toward baseline at 33 in 2024. The 2023 spike likely reflects construction lane closures forcing unusual patterns through this ramp. The subsequent return to baseline in 2024 supports a temporary cause. Hit-and-runs at 17% are consistent with freeway on-ramp patterns.
