The following report is an update for the week of February 8, 2026:
Urgent Notification from Gallatin County Emergency Management: Bozeman area: The eastbound lanes of Interstate 90 (I-90) are closed at mile marker 312 and traffic is being detoured at the Bear Canyon Interchange (Exit 313). MDT is currently routing eastbound interstate traffic around a damaged bridge via the Bear Canyon Interchange on and off ramps. Bozeman Trail Road is not accessible from I-90, and the interstate underpass on Bozeman Trail is closed to traffic. The interstate bridge was damaged on Wednesday when a commercial vehicle attempted to pass under the bridge on Bozeman Trail Road. The load being towed exceeded the bridge clearance of 13’3”. MDT Bridge Engineers have inspected the structure and deemed the closure necessary until repairs can be made or additional information is available. Debris from the structure continues to fall on Bozeman Trail, so travel under the bridge must be restricted. The purpose of the closure is to ensure the safety of the traveling public. MDT will announce further details once they become available. For the latest road condition statewide, go to 511mt.net or download the app.
