Turner–Climax Border Crossing

The Turner-Climax Border Crossing connects the towns of Turner, Montana and Climax, Saskatchewan on the Canada–US border. This facility is one of only six joint US-Canada border stations where U.S. Customs and Border Protection (CBP) and the Canada Border Services Agency (CBSA) share a single facility. The rationale for making this facility a joint border station was primarily for officer safety, since the border stations on both sides of the border were often staffed by only one officer at a time.

Construction on the joint facility was completed in 1992. It is reached from the south via Montana State Highway 241 (MT 241) and from the north via Saskatchewan Highway 37 (SK 37). Along SK 37, the village of Climax lies 24 km (15 mi) north of the Port with the town of Shaunavon an additional 50 km (31 mi) beyond. The unincorporated community of Turner lies 10 mi (16 km) south on MT 241.

The Canadian side is called "Port of Climax", and on the American side is the "Port of Turner"; the latter was built by CBP in 1992. The city of Havre is only a short drive from the Port. SK 37 offers a north-south route to connect with Trans-Canada Highway Route 1 at Gull Lake. The RED Coat Trail Highway 13 at Shaunavon commemorates the role of the North-West Mounted Police in settling the Canadian West.

Some local residents have made efforts to make this crossing a 24-hour facility, in hopes of attracting commercial traffic. On March 16, 2009, the Montana State Legislature passed a joint resolution urging CBP to open the Turner port of entry to commercial traffic 24 hours per day. To date, the port continues to have daytime-only operations in both directions.
