Location: U.S. Hwy 93 / BC Hwy 93
This is the second most heavily used port in Montana with traffic made up of mainly vacation travelers or local autos. However, delays entering Canada can be as long as 3-4 hours during heavy traffic periods. The geography just before the Canadian border crossing constricts traffic and can create huge backups. The solution to this problem is to combine the U.S. and Canadian ports into one building on the American side of the border. As of 2015, that solution is nowhere in sight, so travelers entering Canada should do their best to avoid peak travel periods.
