Two Medicine Road will close Oct. 1 for culvert replacement

Glacier National Park’s Two Medicine Road will close Oct. 1 to replace a deep culvert.

The Park Service said in a release that when the road reopens by late November 2025 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 Park did not immediately respond to an inquiry on whether people could still access the valley by foot, as there is trail access into Two Medicine at the entrance station on the Dry Fork Trail. Presumably trail access would be available over Scenic Point from the Blackfeet Reservation and over Pitamakan and Two Medicine Passes, though those are long walks in the backcountry. 

The culvert work is part of a larger project in the valley slated for next spring. The project includes a full water system replacement, ditch re-establishment, road repair, parking lot construction, replacement of entrance station buildings, and paving.  It should be completed in fall of 2027. 

Construction for that 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-Sept. 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. 

Other projects on tap include:  

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.
