We're retracing our steps for a bit as we head south from Alaska. In general the wilderness-area roads in Alaska and Canada have been good, mostly two lane highways like you will find in rural areas throughout the US. The exceptions were the areas subject to frost heaves, places where the permafrost has begun to melt and the areas where slides have taken out the road along the Alaskan Highway. The most memorable section for everyone I've spoken to has been the area from Haines Junction to Tok. The construction around Destruction Bay has been going on for several years. You can see how small the huge equipment looks as they work to take down a large section of a mountain so that the road can be widened.
