A few notes on the Parks highway between Fairbanks and Anchorage. I drove it twice recently.
Basically the road and bridges are fine, there isn't any earthquake damage - I'm glad that subject has died out.
The Parks has mile post signs up every mile which start at 0 leaving Anch. Having said that there's no earthquake damage, there is a lot of frost heaves in the road between mile post 260 (north of Healy) down to MP 200 (south of Cantwell). Slow down, they can sneak up on you quickly as you go around a corner or over a hill - you won't see them. I was just driving my truck (maybe a little over the speed limit) and left the ground in two spots - you've been warned.
Also further south, a little north of Talkeetna, there's about 25 miles of normal summer road construction with pilot cars. So build stops and slow going into your schedule. As summer gets here there will be additional road construction, but you should be used to it by this point after traveling through Canada.
And remember, or know, that on all main roads in Alaska the freight and fuel trucks are hauling doubles so they're stretched out to 102' in length. This isn't a problem as Alaska builds more passing lanes every year. Stay in the right hand lanes so they can get around you.
