BIG Sky, Mont. - The Montana Department of Transportation (MDT) and project partners continue to make strides on the US 191/MT 64 Optimization Plan, an effort aimed at enhancing safety, mobility, and infrastructure along one of southwest Montana’s most traveled corridors. Multiple transportation improvement projects are currently underway between Four Corners and Big Sky, each with unique objectives and timelines. To keep residents and travelers informed, several resources are available to provide consistent and accessible updates on corridor-related activities.
“These projects are about more than roadway changes,” Geno Liva, MDT Butte District Administrator, said. “They’re about improving reliability, enhancing safety, and supporting growth in responsible ways.”
The US 191/MT 64 Optimization Plan website serves as a comprehensive hub for project information. Here, the public can access project details, interactive maps, project timelines, and understand how this effort will enhance Montana’s transportation system. In addition to details about the Optimization Plan, the website includes updates on related corridor projects, such as:
- US 191/MT 64 Intersection
- Lava Lake Structures
- Spanish Creek Bridge
- US 191 Turnouts – Gallatin Canyon
- Passing Lanes – Gallatin Canyon
- LMC Supply Ditch Structure
- SF 199 Mill Street Intersection Improvements
- Big Sky North
Project milestone updates are shared directly with community members through regular email updates. Anyone interested in receiving future notifications can subscribe by emailing Kristine Fife at Kristine@bigskypublicrelations.com.
Maintenance updates impacting short-term travel will also be posted on the site. Community members are encouraged to visit mdt.mt.gov/pubinvolve/us191mt64/ to stay informed about progress and travel impacts.
Together, these efforts represent a continued commitment to keeping the community informed as we work to enhance transportation safety and efficiency for everyone who lives, works, and travels the corridor.
