The Montana Department of Transportation (MDT) and Coral Construction have completed median high-tension cable rail installation along more than 18 miles of Interstate 15 (I-15) and 14 miles of Interstate 90 (I-90) in the Butte area.
Thank you for your patience and support during this important safety improvement project!
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 second phase of a four-phase safety improvement 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 I-15 in the Butte and Helena areas.
The Bozeman phase was completed in 2023. Construction of the Missoula phase began in September and is anticipated to be completed in 2026. A start date for construction of phase four, I-15 near Helena, has yet to be determined.

Crews will be working on I 15 North, north of the I 15 North and I 90 Interchange, on Tuesday, October 10, and Wednesday, October 11, from 6 a.m. to 6 p.m.
Work on I 90 will occur just east of the Interstate 115 (I115)/City Center Exit, to the east end of the project two miles east of the Montana Highway 375 (MT 375) and Continental Drive Exit. Crews will be onsite Thursday, October 12, and Friday, October 13, from 6 a.m. to 6 p.m.
The left lanes closest to the median on both sides of I 15 and I 90 will be closed where work is underway.
