400-series highways (British Columbia)

The 400-series highways were a pair of controlled-access highways located in the southwestern portion of the Canadian province of British Columbia, forming a special subset of the provincial highway system. Modelled after the 400-Series Highways in Ontario, 400-series designations were introduced in 1964 in conjunction with the completion of the Trans-Canada Highway freeway between Vancouver and Clearbrook (present-day Abbotsford); however, unlike their Ontario counterparts, both routes had signalized sections.
