S Rainbow Blvd

Rainbow Boulevard runs north-south through the western neighborhoods — from the 215 Beltway area down through Spring Valley. It’s one of the western valley’s primary arterials for residents in Desert Shores, the Lakes, and western Spring Valley neighborhoods traveling north-south without getting on the freeway. The road sees heavy commuter volumes during peak hours and serves a mix of residential, commercial, and school-adjacent traffic that creates a consistently complex driving environment.

Crashes dropped from 281 in 2022 to 245 in 2023, then partially rebounded to 270 in 2024. Zero fatalities in 2024 after 3 in 2022 and 1 in 2023 — the fatality risk on this corridor has genuinely declined. The injury trend is worsening (226, 223, 288), consistent with other Summerlin-adjacent corridors: fewer overall crashes but more severe outcomes in those that do occur. The fatality improvement is the headline positive despite the injury trend.
