I-15 North Mainline AT Charleston Blvd

This location captures crashes on the I-15 North mainline in the immediate vicinity of the Charleston Boulevard overpass — distinct from the ramp movements captured at other Charleston/I-15 intersection records. Mainline crashes here reflect lane-change conflicts, speed differentials between slower traffic preparing to exit and faster through-traffic, and the visual complexity of the interchange overhead structure affecting driver attention.

Zero fatalities across all three years, with a notable spike from 16 in 2022 to 42 in 2023 before settling to 34 in 2024. The 2023 increase parallels patterns at several other I-15/Charleston area locations and likely reflects a period of concentrated conflict at this interchange system. The 2024 partial recovery is encouraging but the location remains at elevated crash rates relative to its 2022 baseline.
