I-15 South & Flamingo Rd WB Ramp

The westbound Flamingo Road on-ramp to southbound I-15 handles traffic that has exited the Strip area westbound and is entering the freeway heading south. This ramp’s curve limits sight lines to the merge point, and the proximity to Strip properties means a significant proportion of users are visitors in rental cars making decisions in an unfamiliar environment at the end of an evening on the Strip.

94 crashes, zero fatalities, with an unusual 2023 spike to 45 (from 26 in 2022) before dropping to 23 in 2024. This pattern — of 2023 being an outlier year at multiple Flamingo/I-15 interchange locations — suggests a period-specific factor affecting the entire interchange system simultaneously. The return toward baseline in 2024 is reassuring. Hit-and-runs at 19% are consistent with the ramp environment pattern.
