The Canadian province of British Columbia has a system of numbered highways that travel between various cities and regions with onward connections to neighboring provinces and U.S. states. The numbering scheme, announced in March 1940, includes route numbers that reflect United States Numbered Highways that continue south of the Canada–United States border. Highway 1 is numbered in accordance with other routes on the Trans-Canada Highway system.

Major routes

East–west

North–south

Route list

List is current as of May 2017, according to the British Columbia Ministry of Transportation. All routes are signed with the standard "BC Primary Highway Marker" shield, except where stated as "Unsigned", signed under a street name, signed with the Trans-Canada, Yellowhead, Crowsnest, or Nisga'a route marker, or cosigned with any combination of the above, in the "Notes" column.

Unnumbered highways

The following routes are maintained by the Ministry of Transportation as part of British Columbia's highway system, but they are Currently unnumbered.

Unofficial numbers

Provincially maintained roads with informal or unofficial numbers:

Pseudo routes

Provincially maintained routes which are unnumbered. Route numbers are unsigned and internally referred to as "pseudo-numbers". Pseudo-numbers start with a 9, followed by a two-digit number designating a "transportation district", a colon, and then a four-digit number derived from the province's Landmark Kilometre Inventory system.

Yukon highways in British Columbia

The following routes are within British Columbia but are considered part of the Yukon highway system. Although the Alaska Highway crosses the 60th parallel north, and thus the border with the Yukon, nine times (including six crossings between historic miles 588 and 596), the highway route number changes just once, between Lower Post, British Columbia, and Watson Lake, Yukon. The Yukon section east of here is maintained by Public Works Canada as part of the B.C. portion of Highway 97, while the B.C. section west of here is maintained by the Yukon Government as part of Yukon Highway 1.

Defunct route numbers

The first two freeways built in British Columbia were given 400-series numbers, much like the 400-Series Highways in Ontario. Highways 401 and 499 were renumbered 1 and 99 respectively in 1973. The section of Highway 37 between Terrace and Kitimat was known as Highway 25 until 1986. In recent years, many routes have been devolved to regional and/or municipal authorities and have lost their official highway status, notably the Fraser Highway in the Lower Mainland (formerly part of Highway 1A) and West Saanich Road on Vancouver Island (formerly Highway 17A). Also King George Highway through Surrey was renamed by the City in 2010 to King George Boulevard. (formerly British Columbia Highway 99A).

Defunct lettering system

Prior to 1940, British Columbia classified its major roads with letters. Ultimately, in 1939 or early 1940, a decision was made by the Department of Public Works (now the British Columbia Ministry of Transportation and Infrastructure) to replace the lettering system with the familiar number system. This transition took place during the 1940/1941 fiscal year and led to the installation of route markers along multiple highways.
