A late-night crash on Interstate 84 east of Boise closed the westbound lanes for nearly 13 hours after a driver who had been pulled over stepped out of a vehicle and was struck by oncoming traffic, according to the Idaho State Police. The incident occurred around 10:25 p.m. Saturday, June 27, 2026, near mile marker 67, and drew emergency responders to the scene for an extended overnight operation.
What Happened on I-84
Idaho State Police say the crash unfolded when a vehicle stopped on the westbound shoulder of I-84 near mile marker 67. The driver got out of that vehicle and was subsequently hit by another westbound motorist. Emergency crews responded to assist those involved and worked through the night to clear the roadway.
Westbound lanes remained closed for approximately 13 hours before reopening. The lengthy shutdown had the potential to significantly affect traffic moving through the Treasure Valley corridor, one of the busiest stretches of highway in southwestern Idaho. The exact condition of the person who was struck has not been released publicly as the investigation continues.
Investigation Ongoing
Idaho State Police have not released information on the identities of those involved or the circumstances that led the driver to exit the vehicle on an active freeway late at night. The incident remains under active investigation. No charges or additional details have been publicly announced as of this report.
Crashes involving pedestrians or individuals on freeway lanes — particularly after dark — remain a persistent danger on Idaho’s high-speed corridors. I-84 through Ada County and the surrounding region sees heavy commercial truck traffic and commuter volume around the clock, making any lane shutdown a significant public safety and traffic concern for the Treasure Valley.
Impact on Ada County Commuters
A 13-hour closure of westbound I-84 through the area east of Boise would typically push significant traffic onto alternate routes during morning commute hours. Drivers traveling from communities east of Ada County — including those heading into Meridian, Boise, and Garden City — would have faced detours and delays as emergency personnel kept the scene secured through the night and into the following morning.
Law enforcement agencies across Ada County continue to handle a wide range of traffic and public safety incidents. In a separate recent case, a Meridian man was arrested after a high-speed chase and barricade situation involving Eagle Police, illustrating the range of law enforcement demands on local and state agencies across the Treasure Valley.
What Comes Next
Idaho State Police have not announced a timeline for completing their investigation into the I-84 crash. Additional details — including the condition of those involved and whether any citations or charges may follow — are expected to be released as the inquiry progresses.
Motorists traveling I-84 through Ada County and surrounding areas are encouraged to remain alert, particularly during nighttime hours when visibility is reduced and reaction times are compressed. If you witness a disabled vehicle or traffic incident on a freeway, Idaho law requires drivers to slow down and move over for emergency and response vehicles where possible.
Anyone with information relevant to this incident can contact the Idaho State Police directly. Updates on this case are expected as investigators complete their work.
