WEST GLACIER, Montana — Travelers heading to Glacier National Park in Montana this fall and next spring need to be aware of construction schedules that will close some areas of the park.
Beginning October 1, the park's Two Medicine Road will close to facilitate replacement of a deep culvert. The road will remain closed to vehicles during the culvert replacement. When the road reopens by late November, it may be for vehicle access or for non-motorized use only, depending on the weather. The road normally closes to vehicles at the first significant snowfall.
The culvert work is part of a larger, multi-year Two Medicine Road Rehabilitation and Utility Replacement project, which is scheduled for completion in the fall of 2027. The project includes a full water system replacement, ditch re-establishment, road repair, parking lot construction, replacement of entrance station buildings, and paving.
The Two Medicine utility replacement project is planned to begin in April 2026. Construction for this phase of the project will require spring and fall closures in the Two Medicine developed area and full closure of the campground in 2026. Closures in the Two Medicine developed area will occur outside of concession operating dates (May 22-September 8) and concessioner operated boat tours and the Two Medicine Campstore will remain open. The park will maintain access to hiking trails as feasible, but access to some trails may be limited.
St. Mary
Additional utility replacement is planned to begin at the St. Mary Campground, the administrative area, and around the visitor center in 2026. The St. Mary Campground will be temporarily closed for construction of the new water system during the winter and possibly the spring of 2026 but will reopen by July 1, 2026. The St. Mary Visitor Center will maintain its normal seasonal schedule.
Many Glacier
In 2025, Many Glacier Campground was closed due to the Swiftcurrent area water system replacement and utility project. The Many Glacier Campground is expected to reopen mid-May 2026. The Swiftcurrent area closure began in September 2024.
Lake McDonald Lodge, Many Glacier, and Granite Park Chalet
Design is underway on additional utility system replacement projects at Lake McDonald Lodge Developed Area, Many Glacier Hotel Developed Area, and Granite Park Chalet. These projects are currently in design with construction planned to begin in the fall of 2026 or spring 2027. Check the Road Construction and Infrastructure Project Work page on the park website for more information on construction in the park.
Alternative camping accommodations are available outside the park. For detailed information regarding campgrounds on the Blackfeet Reservation, please refer to the Nearby Camping page on the park’s website.
