We were hoping that Sen. Ted Stevens could get us a bridge built from the Alaska-Canada border to the Canada-Washington border, thus denying access to those pesky Canucks.
As to restricted access highways: besides the short portion of the Seward Highway that fits the definition, there is Minnesota Blvd and most of the Glenn Highway between Anchorage and Palmer that is four (and at times six) lane divided. Also, the few miles of the Parks Highway between the Glenn Highway cutoff and Wasilla.
Ethilrist: “major city” is a relative term, of course. After Anchorage (pop. 250,000), the next in line is a toss-up between Fairbanks and Juneau (pops. about 30,000). It goes rapidly downhill after that. All of the towns in Southeast Alaska are inaccessible by road, with the exceptions of Haines, Skagway, and one other very small town I can’t recall. All of those roads originate in Canada.
Fairbanks and many other towns are on the road system, but nearly all Native villages are accessible only by air or sea. The largest of those is Barrow at about 4,000, followed by Nome and Kotzebue at around 3,000.
