Yukon River is the biggest and longest river in Alaska. To find out more about it go to http://en.wikipedia.org/wiki/Yukon_River. Approximately 136 miles from Fairbanks to the Yukon River bridge. It is about at least 40 miles of rough road on the Dalton Highway. There are a few spot of pavement here and there and it just enough to make you appreciate it. I found it weird though to see a sections of pavement in the middle of nowhere. The pipeline and the scenery are gorgeous, especially the leaves are turning colors. Motel by the bridge. If you plan to come here, make sure to bring a bunch of snacks because this is the only place you can get something to eat for at least 100 miles.
