British Columbia provincial highway 22 is a north-south highway that provides quick access from the city of Canada-U.S. border. When the highway was first opened in 1964, it only went as far north from the border as Rossland. Highways 3 and 3B followed the present-day routing of Highway 22 north of Rossland at the time Highway 22 was first opened. The route north of Rossland was given to Highway 22 in 1979. The number of the highway is derived from Washington State Route 25, which Highway 22 meets at the border. Washington State Route 25 was numbered 22 prior to 1964.
