Editing Route number (section)

===Canada===
{{main|Numbered highways in Canada}}
The [[Trans-Canada Highway]] system is made up of a series of provincially maintained highways, and is one of only two systems (the other being the [[Crowsnest Highway]]) that uses route numbering that spans multiple provinces, albeit not across the entire country. The provincial highways are assigned numbers by their respective provinces.

====Alberta====

*500-986 Series — local highways

====British Columbia====

{{main|List of British Columbia provincial highways}}
Owing to the mountainous terrain in the province, route numbers are assigned on a mostly [[ad hoc]] basis, and vary between west–east and south–north routes.  They currently span from 1-118, except for Hwy 395 which is a counterpart of US 395.  Some routes are grouped in numerical patterns (e.g. Highways 9, 11, 13, 15, 17, and 19 are north–south routes with values increasing by increments of two moving West). British Columbia formerly had "400 series" of highways similar to Ontario, but that scheme was dropped in 1973.
