This four mile Norwegian road zig-zags across seven different bridges, with many so low that waves hit the pavement. And during Norway's cold, snowy winters, the road gets even more terrifying. But in decent weather conditions, the view alone is worth it.
This highway that stretches along the Baja California Peninsula (it becomes Interstate 5 in the U.S.) twists and turns through mountains and cliffs. It's almost entirely lacking of shoulders or guard rails, making it a particularly tough road to navigate.
These roads are built right into the Himalayan Mountains, which pretty much tells you all you need to know about how dangerous they are. However, if you do travel along these roads, you'll get a great view and possible spot some rare birds, like Himalayan griffons or golden eagles!
At its highest point, the Halsema Highway is 7,400 feet above sea level, and prone to mudslides and landslides. This is why it's particularly recommended to avoid this road during the rainy season (June through September).
Fortunately, the picture above is a distorted 3D image from Google Earth, not real. But there are plenty of real, actual roads whose twists, turns or other unsavory conditions make this crazy dip look like a walk in the park.
There are only three villages along this 414-mile highway, making it an extremely isolated road. It also means there are just three opportunities to get fuel. That, plus steep gradients and Alaska's frequent snow and ice, helped the Dalton Highway make appearances on shows like Ice Road Truckers and World's Most Dangerous Roads.
This series of highways spans the entire length of Russia, which means it covers some pretty rough patches of forest and tundra. These parts of the road are made even more dangerous during the icy Siberian winter.
Located in Siberia, this single-lane rickety wooden bridge with no rails can only be crossed by the steadiest of drivers. Instead of crossing it yourself, you're better off watching this video of someone else doing it. Yikes!
