Editing Route number (section)

====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.
