Generally highways in the 1–216 series are major highways (except when they are freeways), and highways in the 500–999 series are minor highways. However, a highway with a letter suffix in its number should generally be one type lower than the corresponding highway without the letter suffix. For example Hwy 2A is a major highway, one type lower than Hwy 2 (freeway), and Hwy 13A in Camrose is a minor highway, one type lower than Hwy 13 (major highway).
Township and Range Roads
Township and range roads are maintained and signed by the local municipal district (MD). Some MDs have chosen a numbering format with a hyphen before the last digit (e.g. “Township Rd 38-4”) but most have chosen a hyphenless format (e.g. “Range Rd 15”). In WME, the road names should follow the local format as used on the signs. Abbreviate “Rd” but leave “Township” and “Range” unabbreviated.
Township and Range roads are not highways and should be (at highest) Primary Street.
