I-15 North

I-15 North is the spine of Las Vegas. Every local who commutes, every visitor leaving the Strip, every truck delivering to the northern valley uses it. At 4,027 crashes over three years, it’s the single most crash-intensive road in Clark County by a significant margin. Locals have a specific mental geography of this freeway’s risk — the US-95 interchange where the two primary freeways braid and separate, the compressed section through the downtown core, and the Spaghetti Bowl where speed differentials between express and local lanes create constant lane-change conflicts.

The 915 hit-and-run incidents over three years represent a driver fleeing the scene roughly every 35 hours on this single corridor. The freeway environment makes fleeing easy: acceleration, distance, and limited witness opportunity all favor the driver who makes the wrong choice. Late-night casino traffic merging with early-morning commercial trucks creates a specific impairment and fatigue window that shows up in the alcohol and fatality data.

20 fatalities over three years — the county’s most concentrated death toll on a single road. The count spiked to 10 in 2023 before falling to 9 in 2024. Crashes have shown modest improvement overall: 1,393 in 2022, 1,288 in 2023, partially rebounding to 1,346 in 2024. That’s not the trajectory any transportation planner would want, but it beats the alternative.

The hit-and-run rate of 22.7% — nearly 1 in 4 crashes — is among the highest of any corridor in the dataset. Alcohol involvement in 162 crashes across three years reflects the freeway’s dual role as a commuter spine and a departure route from the valley’s entertainment corridor. I-15 North is the county’s most urgent freeway safety priority.
