Trans-Siberian Highway, Russia
Along with the Trans-Canada Highway and Australia’s Highway 1, the Trans-Siberian Highway is one of the longest in the world. In order to get from Vladivostok to St. Petersburg, it crosses forests, mountains, deserts, and everything in between. Much of it is unpaved and certainly not ideal for a casual Sunday drive.
Highway 1, Mexico
While some parts of Highway 1 in Mexico are paved with asphalt, most of it is little more than dirt and rock, winding along dangerous precipices with no railings or guard rails.
Stelvio Pass Road, Italy
Cotopaxi Volcano Road, Ecuador
Although there are many dangerous sections branching off the Pan American highway, the 40-km long dirt track that links it with the Cotopaxi Volcano National Park in Ecuador tops the list. With enormous potholes, slippery slopes, and all around precarious driving conditions, this a road a bit of a challenge.
Pan-American Highway, Alaska to Argentina
As we just saw, many dangerous roads branch off the from the Pan-American Highway, but the highway itself can be fairly dangerous as well. It has been named the “longest motorable” road in the world as you can travel by car from the stretches of Alaska down to the tip of South America, which is about a 30,000 miles in total. As you can imagine, crossing two continents and traversing through jungles, mountains, glaciers, and deserts can inevitably lead to some challenges.
