[2] In 1904, the St. Mary's NWMP moved to Twin Lakes (present day Police Outpost Provincial Park, about 6 kilometres (4 mi) westward).

Based about one mile north of border, the NWMP collected duties until a regular customs office opened, which operated from 1912 until 1932.

Canada Customs officer Herbert Legg created the name by combining the words Cardston and Highway.

[10] In 1933, the US built a log cabin-style border station, which is on the National Register of Historic Places.

[11] The US built a new facility in 2003, but the historic border station still stands a short distance to the south.
