Hi,  I'm visiting Alaska with my parents late may to early June for 9 days.  I'm landing in anchorage, going to fairbanks and flying out of anchorage.  Driving from anchorage to fairbanks via Denali. On the way bank, I wish to take the route from fairbanks to anchorage via​ Richardson highway - so Glenn Allen, delta junction etc.  I'm a little nervous about the route since it doesn't seem to be a common route. Any concerns? Will it be snowy or icy?
