Interstate Highways in Alaska

There are Interstate Highways in Alaska that get money from the government. Even though these are Interstate Highways, most of them are not grade separated, which means drivers must use a specially made group of ramps to get to the road. They mostly are along roads with two lanes. Also, there are no signs for these Interstate Highways.
