Risk Factor: How harrowing is the drive along the Dalton Highway? It's so intense that they made a reality TV show about it. The fourth through sixth seasons of the History Channel's Ice Road Truckers focus in part on the Dalton Highway, a road built in the '70s to bring supplies along the Trans-Alaska Pipeline. (It was also featured in an episode of the BBC Two's Most Dangerous Roads.) Along the 414-mile route, drivers are subjected to freezing temperatures, gravel roads, avalanches, whiteout snowstorms, as well as a general lack of cell phone reception or service stations. There's a reason this drive is mostly attempted by truckers—and, even then, with lots of spare tires and at speeds slower than 55 mph.
Why you might be tempted to drive it anyway: Besides getting to say you've driven on the northernmost highway in the continent, taking the Dalton is the only way drivers can get access to the Brooks Range, where there's unspoiled landscape to be hiked, especially through the Gates of the Arctic National Park and Preserve.
