On the primary/trunk edge cases, particularly on the "major highway/freeway cancelled after construction started" type situation, the relative lack of driveways and relative prevalence of ramps along with historical context might be the only claim to the very lowest end of trunk on a dual carriageway and potentially highest end of primary for a single carriageway (I'd only consider a single carriageway to be a trunk if it's completely controlled access with no at grade intersections or driveways). > I'm a novice with highway tagging of this sort but if any of you more > experienced mappers would care to take a look at those two highways, any > feedback would be appreciated. > I'm a bit rusty on my Alaska geography, so if you got a relation or way ID to work with, that might help. Excluding the unpaved primaries that I'm aware of that compose most of Alaska DOT's mileage, I'd hazard to guess Alaska has considerably more "trunk" than "motorway" miles, particularly outside of metro Anchorage.
