Route Length: 414 miles
"I chose Alaska's Dalton Highway as my favorite, as it’s a road that reaches the top of the continent, and would literally allow you to see a polar bear in the right circumstances," Martin said.
"The Dalton Highway is one of America's harshest and most remote routes. We’re talking 240 miles between services and only a handful of small towns along the way. It’s mostly the 'ice road truckers' who make the difficult journey along this gravel highway, travelling through Alaska’s boreal forests, across its vast mountain ranges, over the Yukon River, all the way to the Arctic Ocean."
