The Montana Department of Transportation (MDT) and Coral Construction have completed installing median high-tension cable rail along more than 40 miles of Interstate 90 (I 90), from Three Forks east to the Bear Canyon exit, east of Bozeman.
Thank you for your patience and support during this important safety improvement project for the Bozeman area!
Median high-tension cable rail has been proven to reduce the severity of crashes and prevent fatal crashes caused by vehicles crossing the median into oncoming traffic.
This project is the first phase of a four-phase project that will install 150 miles of median high-tension cable rail along sections of I 90 in the Missoula, Butte, and Bozeman areas, and Interstate 15 (I 15) in the Butte and Helena areas.
Construction of the Butte phase began on October 9. Work has paused for the season and will resume in the spring. The Butte phase is anticipated to be completed in 2024. This schedule is subject to change due to unforeseen circumstances, such as weather and project material availability.
