I-15 North TO Sahara Ave

This on-ramp interchange — where northbound I-15 meets the Sahara Avenue overpass — is one of the busiest merge points on the freeway system serving central Las Vegas. Locals heading to the northern valley or connecting to US-95 use this ramp daily. The weave zone between merging Sahara traffic and through freeway traffic creates consistent rear-end and sideswipe conditions. The nearby north Strip casino properties add tourist-origin traffic — drivers who may not know the ramp timing or lane configuration.

162 crashes over three years at a single on-ramp, with zero fatalities across all three years, and crashes dropped significantly from 86 in 2022 to 38 in both 2023 and 2024 — a 56% reduction. Something changed here in 2023 and the improvement has held. The hit-and-run count of 25 (15%) mirrors the freeway ramp pattern where acceleration away from the scene is straightforward.
