Project Overview
The Montana Department of Transportation (MDT) will begin a four-phase road safety improvement project by installing high-tension cable rail along sections of Interstate 90 (I 90) in the Missoula, Butte, and Bozeman areas and Interstate 15 (I 15) in the Butte and Helena areas. From start to finish, the Median High-Tension Cable Rail project will add high-tension cable guardrail across 150 miles of Montana’s roadways.
Built with safety in mind, the High-Tension Median Cable Rail project will provide a flexible barrier of steel cable mounted on steel posts in the center median. The high-tension cable rail reduces crash impact and redirects vehicles from crossing into opposing traffic.
Construction on phases one and two, the Missoula and Bozeman areas, will begin in late April.
Poteet Construction was awarded the Missoula phase of the project, which includes 48 miles of high-tension cable rail installation on I 90, spanning from west of Missoula near Wye east to exit 144 at Bearmouth.
Coral Construction Company will be constructing the just more than 40-mile Bozeman area section, from Three Forks east to Bear Canyon. The company was also awarded the Butte area section, scheduled for construction in 2024.
Both the Missoula and Bozeman area phases are expected to be completed in 2024; however, this schedule is subject to change due to weather and other unforeseen circumstances.
MDT anticipates minimal travel impacts; however, minor travel time delays are expected. Motorists should expect single-lane closures and reduced speeds when passing through active work zones.
