I-15 North Mainline AT Sahara Ave

This location captures crashes on the I-15 North mainline in the immediate vicinity of the Sahara Avenue overpass — a stretch where lane changes, speed differentials, and the proximity of multiple ramp movements create a concentrated crash zone. Locals who commute northbound daily have a specific mental flag for this section: move left early, know the right lane exits to Sahara, and watch for the visitor in a rental car cutting across three lanes at once.

Crashes increased sharply from 15 in 2022 to 49 in 2023 and 46 in 2024 — a 200%+ increase from baseline. The single fatality occurred in 2024. This upward trend, counter to improvement at many other freeway locations, suggests a worsening condition rather than random variation. Whether this reflects construction-related lane shifts or changed traffic patterns, this location warrants close NDOT attention.
