Thank you @AlasSouth! I looked at the Alaska map in my road atlas and nowhere does the map show the red, white and blue shield that denotes the Interstate Highway system. So even if those A-marked roads in Alaska may be up to interstate standards in some areas, they are not the genuine Interstate Highway article!
One criteria that may be confusing is an Interstate Highway has to have at least four lanes. Many of them do, but I-95, that famous Interstate that goes from Maine to Florida, has (or had) one exception.
Admittedly I haven't been up that way in years but for a long time I-95, once it got much beyond the Bangor-Old Town area, dwindled down to only two lanes of undivided highway. It was still limited access but with traffic going in both directions. That northernmost portion goes through Aroostook County which most likely doesn't have the population to support a highway with four lanes.
But if anyone has been up that way recently please update me if I-95 has been expanded to four lanes.
However, the atlas does show a small Interstate network in Hawaii, H-1, H-2 and H-3, which goes through Honolulu and out into the suburbs on Oahu.
And it's interesting and not just a little shocking that there are companies in the "Lower 48" that still aren't convinced Alaska is a part of the U.S. and that it's still on the North American continent!!! Very interesting indeed!!
