In the US, it's generally established that state highways are highway=secondary, even if unpaved, in the lower 48 and Hawaii. Though the "unpaved" part has been obsolete since AR 220 went from surface=dirt (it wasn't even graveled) to surface=asphalt, 4 years ago in two weeks in the lower 48 and Hawaii. Alaska is currently the only state, territory or posession of the US that has unpaved state highways and the last of the same that will ever have unpaved highways in the Eisenhower Interstate Defense Highway System (despite having no signed network US:I routes presently). With that context, AK 2 fits pretty obviously as highway=secondary. Based on my look just now, looks like that's a good fit saved for portions within Fairbanks metro, which would be a good highway=trunk segment. There are no portions that I see as rising to highway=motorway, despite being presently mapped as such in some parts of Fairbanks.
