The bridge outside (west of) Paxton was being reconstructed when I traveled on the road this spring... CHECK to see if it's finished. my 7ft wide travel trailer BARELY FIT across the portion of the bridge that was open, and the fifth wheel ahead of me was denied crossing, had spent the night at the bridge and was heading back to Cantwell.
I'm very chicken when it comes to towing on rough roads, so AK 8 was a LONG DRIVE for me, my truck and my TT... most of the time I was going 25-30 mph. It was a very rough gravel road with plenty of pot holes and heaves / dips.
Several other travelers blasted by driving truck campers and class c type rigs doing 50-60 mph; I guess their suspension was much better than mine.
if your 5th is the kind that has lots of clearance, you'll find plenty of places to pull off and rest or camp for the night... I found many of the sidings having numerous deep mud ruts in them, I considered unsafe pull off with my very low slung tt.
As rough as the drive was, the Denali Highway was one of the favorite things I did in Alaska. Once the sun started setting, traffic stopped on the road and it was so very very quiet and peaceful. As the sun set, big fluffy snow flakes were falling around me (early June); it was an outstanding night.
