The White River to Destruction Bay portion is actually in pretty good shape right now due to the major reconditioning of the Alaska Border to Destruction Bay portions the Yukon Government is committed to since 2013....
What normally takes me an average of 3 hours and 45 minutes (sometimes over 4 hours) or so to drive non stop from Destruction Bay to White River (83 miles) as I take my time and not ruin my old rigs...
As of last year in 2017 it only taken me 1 hour 54 minutes and 1 hour 56 minutes to drive in both directions - quite a record shattering time hauling my camper thru that kidney beating stretch that was the norm...With that said, construction will still continue somewhere well south of Donjek River although I noticed some improvement in portions south of the river already.
In 2010, the Destruction Bay thru the Border stretch was thee worst condition I have ever seen it to this day...way worse than my very first drive in 1985.
Needless to say, the stretches of Alaska Highway from Destruction Bay thru 3 miles (past) west of Northway Junction never holds up on a long term basis...
It didn't even take a year before the Koidern area of roadway already buckled up, and I seen total resurfacing 4 times since 1989 between Northway Junction and the border at Port Alcan on the Alaska side...
The stretch between Mirror Creek and the border on the Yukon side since the 2013 and 2014 reconstruction period has already tarnished back to it's old ways in a lot of spots too...
I still have pictures thru this notorious Destruction Bay thru the Border stretch taken in 1994 when it was still narrow in most places, while in 1998 on my next trip in Canada I seen the widening and substantial improvement of the Destruction Bay thru the Border stretch but had mixed feelings about it because all the old ruggedness of the Alaska Highway was totally gone, like it lost it's true identity...
Fast forward to a 10 year gap on my next trip in Canada on the Alaska Highway portion of the Yukon in 2008 as I couldn't believe how the entire Destruction Bay thru the Border stretch was back to it's normal frost heaved buckled condition that I witnessed, like they didn't do anything to the roadway other than widening some shoulder space with a couple short bypass routes away from the Kluane River....so the Spirit of the Yukon remains alive and well thru this famous frost heaved stretch of the Alaska Highway.
