I-15 South & Sahara Ave Ramp B

The second Sahara Avenue ramp on southbound I-15 serves eastern approach traffic from the UNLV area, east-side residential neighborhoods, and the E Sahara commercial corridor onto the freeway southbound. The merge zone here is compressed and the speed differential between ramp and mainline traffic creates consistent conflict. One fatality in 2022 occurred at this location in a year when crash counts were nearly three times higher than in subsequent years.

One fatality in 2022, then zero in subsequent years, combined with a significant downward trend (53, 24, 17 crashes) tells a story of genuine improvement. The 68% crash reduction from 2022 to 2024 is among the steepest at any freeway ramp in the dataset. Whether this reflects physical changes to the ramp, changed traffic patterns, or enforcement is unclear, but the trend is unmistakably positive. Hit-and-runs at 24% are elevated, consistent with freeway ramp patterns.
