Fatality crash I90 near milepost 40, Cataldo, Shoshone County

The Idaho State Police is investigating a fatality collision which occurred on November 15, 2025, at approximately 1:55 p.m.

At that time, a Black Mazda CX-5 was traveling westbound on I90, near milepost 40. The Mazda, driven by a 25-year-old male from Lolo, Montana, failed to negotiate a left-hand curve. The Mazda left the roadway at the right shoulder and traveled along the roadside where it then overturned. A 25-year-old female passenger, from Missoula, Montana, was ejected from the vehicle.

Shoshone County Sheriff’s Office Deputies and the Idaho State Police responded. The driver was transported to a nearby hospital via ground transportation. The female passenger was transported, via air ambulance, to a nearby hospital. The female was later pronounced deceased at the hospital.

Neither occupant was wearing a seatbelt. At the scene of the crash, the roadway was restricted to one lane for construction. The single lane of travel was blocked for approximately one hour for medical personnel to assist those involved and opened thereafter for the remainder of the on-scene investigation.

This investigation is ongoing.
