Dear Community Members,

This is to inform you of an upcoming roadway patching project in the Gallatin Canyon, scheduled to begin on Monday, September 22, 2025, weather permitting.

The work will be performed by Montana Department of Transportation (MDT) maintenance crews and will focus on repairing deteriorated pavement sections along U.S. Highway 191in the Gallatin Canyon North of the highway 64 intersection. This patching effort is intended to improve driving conditions and safety in the short term while preparing the corridor for a much larger and more permanent construction project, which is currently slated for bid in 2026.

Project Details:

• Start Date: Monday, September 22, 2025
• Work Hours: 8:00 AM – 3:00 PM (weekdays only)
• Location: Gallatin Canyon, U.S. Highway 191
• Contractor: MDT Maintenance Forces
• Scope: Asphalt patching and surface repairs to address immediate pavement concerns
• Duration Work is scheduled to be completed within two weeks.
• Traffic Impacts:
  • Single-lane closures with flaggers
  • Reduced speeds through work zones
  • Delays expected during working hours

To minimize disruption to commuter traffic, all work will be conducted outside of peak travel hours. Drivers are encouraged to plan accordingly, allow extra travel time, and use caution when traveling through the work zone.

We appreciate your patience and understanding as we complete this necessary interim work. These repairs are a temporary measure to maintain safety and drivability until the full-scale reconstruction project begins next year.

If you have any questions or would like more information, please don’t hesitate to reach out.

Milling and paving work on Highway 64, from the intersection at U.S. Highway 191 to milepost 3.8, has been awarded to a contractor and is scheduled to be completed this fall. This project will involve removing the existing surface and applying new asphalt to improve roadway conditions, enhance safety, and extend pavement life. All work will be completed at night to reduce impacts on daytime traffic. We will provide updates with more specific scheduling and traffic control information as it becomes available. Drivers should anticipate nighttime lane closures and reduced speeds during construction and are encouraged to plan accordingly.

Best regards,
Josh Ritchie

Important information about an upcoming Montana Department of Transportation (MDT) scrub seal project on Highway 64, scheduled to begin Monday, August 11, 2025.

The project will run from MM 3.80 near Lone Mountain Ranch westerly to the intersection of Sitting Bull Road (near Big Sky Resort) at MM 9.0, and while all work will take place above Big Sky Town Center, traffic impacts may still be experienced throughout the community.

Project Schedule & Traffic Impacts:

• Monday, August 11: Minimal traffic impact expected. The contractor will clean the road surface and address cracking, starting near the fire station. This work should take one day.
• Scrub Seal Application: Planned for Wednesday, August 13 or Monday, August 18 (depending on contractor schedule). This portion will take two days—one for the seal application and one for cleanup. The contractor will mark traffic lanes with reflective tabs.
• Pavement Marking: MDT will repaint the project area the day after cleanup.

Traffic Control & Notifications:

• Variable Message Signs (VMS boards) will provide advance warning.
• The contractor will manage on-site traffic control.
• MDT is coordinating with the Helena office to share updates via social media.

About the Work:
The scrub seal process helps extend the life of the pavement by sealing cracks, improving surface texture, and protecting against moisture penetration—ultimately leading to a smoother, safer driving surface.

Thank you for your patience and safe driving during this important maintenance work.
