Interstate Highways in Alaska

Map of the Interstates of Alaska

There are four officially designated Interstate Highways in Alaska, even though 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 other states; however they are not signed with interstate highway shields.

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. Limited-access freeways exist only within and near Anchorage, Fairbanks, and Wasilla.
