The Municipality of Crowsnest Pass is bounded on the west by the BC/AB boarder and on the east by the municipal district of Pincher Creek.

Alberta Highway 3 passes through this municipality.

My edits in Changeset: 145865015 are as follows.

Change https://wiki.openstreetmap.org/wiki/Tag:highway=trunk to https://wiki.openstreetmap.org/wiki/Tag:highway=primary

From the Canada Tagging Guidelines for Primary Roads primary roads are typically 2-lane, undivided, provincial highways. This description is accurate for Highway 3 through the Crowsnest Pass.

See also the Alberta Highway Classification Guidelines

https://wiki.openstreetmap.org/wiki/Tag:highway=trunk, however, is suggested for “the national highway system”.

Contrary to my change, the National Highway System page on Wikipedia lists Highway 3 as a core road in the national highway system. This may need reversion.

Change to https://wiki.openstreetmap.org/wiki/Tag:name=20 Avenue and https://wiki.openstreetmap.org/wiki/Tag:nat_name:en=Crowsnest Highway

Within the Municipality of the Crowsnest Pass, Highway 3 is labelled on street signs as 20 Avenue. This is similar to how Highway 1 is also 16 Avenue through the City of Calgary.

The Canada Tagging Guidelines for Named Major Highways explains that when a named highway also has a street name, tag:name should be used for the street name and tag:nat_name should be used for the highway name.
