A woman is dead following a pre-dawn crash on Interstate 90 near Mullan, Idaho, after she was struck by a semi-truck in the eastbound lanes of the highway, the Idaho State Police reported Thursday.
The Idaho State Police is investigating the fatal collision, which occurred at approximately 1:52 a.m. on Thursday, April 10, 2026, near milepost 64 on eastbound Interstate 90 in Shoshone County. The crash involved a red semi-truck and a female pedestrian who was on the roadway at the time of the strike.
The semi-truck was driven by a 30-year-old male from Mountlake Terrace, Washington, who was traveling eastbound on I-90 when the vehicle struck the woman. The pedestrian succumbed to her injuries at the scene. As of the time of the report, she had not been positively identified by authorities.
Eastbound I-90 Lanes Closed for Hours Following Crash
The fatal crash prompted a significant response from emergency responders and investigators in the early morning hours near Mullan, a small community in the eastern end of the Silver Valley along the Idaho-Montana border. The eastbound lanes of Interstate 90 were blocked for approximately three and a half hours as law enforcement worked to secure the scene and conduct their investigation.
Interstate 90 is a vital east-west corridor through Shoshone County, connecting the Silver Valley communities of Wallace, Kellogg, Osburn, and Mullan to the rest of northern Idaho and the broader Northwest. Commercial truck traffic is heavy along this stretch of highway, which serves as a primary freight route through the region.
A closure of the eastbound lanes for several hours in the middle of the night would have affected overnight commercial traffic moving through the mountain corridor near Lookout Pass, one of the more challenging winter driving segments on I-90 in northern Idaho.
