Interstate Highways in Alaska
From Wikipedia, the free encyclopedia
There are four officially designated Interstate Highways in Alaska, even though Alaska is usually considered to have no interstates, and the routes do not connect directly to any highways in the contiguous United States, except either by the Alaska Marine Highway System ferries or via Canadian highways.
These routes are numbered A-1 through A-4 and receive similar funding to interstates in the Lower 48, but are unsigned (unlike those in Hawaii) and exist only on paper.
They follow various combinations of Alaska Routes, which generally fail to meet Interstate Highway standards, being for the most part two-lane rural highways without controlled access. The federal government established the classification of these roads as Interstate Highways primarily for funding purposes. There appears to be no indication that upgrades to Interstate Highway standards will be made, aside from a few heavily traveled urban corridors.[original research?] Limited-access freeways exist only within and near Anchorage, Fairbanks, and Wasilla.
