MONTANA: The United States is set to close a historic cross-border road to Canadian traffic later this summer, ending a decades-old local arrangement along the frontier near Coutts, Alberta, and Sweet Grass, Montana. The road, known as Border Road, runs for about 14 kilometres along the boundary and sits on the Montana side, even though Alberta has long maintained it. The change will require Canadians who use the route to move through the official port of entry instead of travelling the shared local road.
Border Road has for generations been used by farmers, ranchers and nearby families on both sides of the line to reach property, move between fields and visit neighbours. The gravel road was built in the 1940s and has functioned as a practical local route in an area where communities on either side of the boundary have long-standing social and economic ties. Residents and local officials have said the arrangement also reflected shared upkeep, with Americans supplying gravel and Alberta handling maintenance.
Once the restriction takes effect, Canadians who have relied on the road will need to detour through the Coutts and Sweet Grass crossing, adding travel time for trips that local residents had long treated as routine. The road’s closure will not affect the formal border crossing itself, which remains the designated route for legal entry between the two countries in that area. What changes is the long-standing local access to the parallel road that sits on U.S. soil but has served both sides.
Local Access Ends
Alberta Transportation Minister Devin Dreeshen has said the province was informed last year by the U.S. Department of Homeland Security that access on U.S. soil at the border would be more strictly enforced. Residents in the area have also said U.S. border officials told them the change was tied to wider concerns about illegal traffic and unauthorized crossings along the border. No separate public U.S. federal notice was readily available detailing the local closure, but Alberta officials say the decision is now being implemented.
Alberta’s 2026 budget includes a C$8 million allocation for what it calls Border Road Reconstruction in Warner County, funding construction of a new local gravel road on the Canadian side of the boundary. Dreeshen has said the province is working with the County of Warner to preserve local access for Albertans once the U.S. side is closed. Provincial officials say construction is scheduled to begin in April, with completion targeted for the summer, creating a parallel route running just metres north of the existing road.
Replacement Route Planned
The practical effect is that a single shared strip will become two separate local roads divided by the international boundary. Residents on the Canadian side will use the new Alberta route, while the Montana side will remain under U.S. control and no longer be open to routine Canadian traffic. The change also alters the maintenance arrangement that had existed for years, because Toole County and local U.S. authorities will be responsible for the Montana road without Alberta’s role in day-to-day upkeep.
For the ranching and farming communities around Coutts and Sweet Grass, the closure marks the end of one of the most visible examples of the informal daily ties that shaped life along this stretch of the border. The road itself will remain, but the cross-border convenience attached to it will not. In its place, Alberta is moving ahead with a Canadian-side route designed to keep local traffic moving while complying with the new U.S. enforcement approach. – By Content Syndication Services.
