Dalton Highway, Alaska
One of the world’s most isolated roads (and a regular fixture on all-American bucket lists), this icy finger of tarmac was built in 1974 as a supply route for the Trans-Alaska Pipeline System. Tackle this route and you’ll need to pack plenty of supplies; there are just three towns on the (eerily) 666 kilometre route, one of which is named Deadhorse. To complicate matters, large sections have fallen into disrepair, and its most famous claim to fame is a reminder that this isn’t a highway you want to break down on: It’s the longest stretch of road in North America without roadside services of any kind.

Atlantic Road, Norway
This twisting ribbon of coastal concrete might well look rather beautiful but don’t be fooled; it’s one of Norway’s most dangerous roads. Drive along it and you’ll feel as though you’re on a rollercoaster ride, thanks to the sharp turns, curves, and twists. When the weather’s bad—as it often is, in this part of the world—visibility can disappear in a matter of seconds. And then you’ve got the waves, huge, thundering walls of water which regularly crash over the road’s barriers.

North Yungas Highway, Bolivia
Scarily, this narrow road clinging to the side of a Bolivian mountain was once the main route into the country’s capital, La Paz, which holds the honour of the world’s highest capital city. Authorities eventually built a shiny new highway, but locals still speed down this road that also serves as a popular mountain biking spot. There are several reasons not to look down. One of the most unnerving sights is the dozens of makeshift memorials dedicated to those who’ve lost their lives here. The road has a total drop of 12,000 feet and even today, between 200 and 300 people die on the road every year.
