Here's another great online resource - Bell's Alaska Highways
It has a mile by mile listing for every highway - and you can print off what you need.
Plus it covers every road in Alaska, the Yukon, and northern BC.
Actually, the Alaska Highway isn't all that remote. That's why it has lost some of its allure for me. There are more remote paved roads in Nevada, Wyoming, and eastern Oregon - not to mention dirt ones. If you take a look at Bell's, you will see that there are facilities about every 30 to 50 miles.
From Tonopah to Ely in Nevada it's 170 miles with one little store that's part of someone's ranch which might be open or not. Plus the national forest has no trees and there's precious little water. From Watson Lake to Teslin - one of the more remote stretches - there are rest areas with covered shelters, campgrounds - both territorial and private, gas stations, and lodges. Plus there's a pretty steady stream of traffic in the summer. Not awful - just steady.
The Campbell Highway - from Watson Lake to Carmacks - is extremely remote. I wouldn't try it unless you have considerable touring experience, experience touring all day on gravel, plus backcountry skills. For a quieter ride that's less daunting, consider the Stuart Cassiar. Then if you are totally comfortable when you reach Watson Lake - take the Campbell. One drawback of doing the Campbell thru Dawson City is that you will miss Kluane.
Good luck in your planning and your trip.
