1. Milford Road, New Zealand
Not to be confused with the famous Milford Track trekking route, the Milford Road State Highway 94 passes through the Southern Alps of New Zealand’s South Island.
6. I-70 at Glenwood Canyon, Colorado
The Colorado River, of Grand Canyon fame, carved this canyon billions of years ago. The U.S. government built the 12-mile, $490 million interstate route through it, which was only completed in 1992.

7. Millau Bridge, France
Southern France’s Millau Bridge is the tallest in the world — taller, actually, than the Eiffel Tower.
8. Karakoram Highway, Pakistan
The “highest paved international road in the world” connects Pakistan with Xinjiang, China. It is currently closed at the Hunza Valley due to a massive landslide.

9. Mountain road, Snowdonia, Wales
Mountainous northern Wales is traversed by many of these ancient, narrow, stone-walled roads. I’ve experienced the challenge of navigating them at night. With oncoming traffic. Car renters beware.
10. Ice Highway, Canada
Winter means greater accessibility in northern Canada. This frozen road runs up the Northwest Territories.
11. Chapman’s Peak Drive, South Africa
Another great coastal road, this one just 15 miles south of Cape Town.

12. Mountain road, central Peru
Most mountain pass roads in Peru qualify as “spectacular.” This one runs north from the Sacred Valley town of Ollantaytambo and is part of the car route to Machu Picchu.
16. Seven Mile Bridge, Florida Keys
U.S. Highway 1 runs for miles over the water, connecting the Florida Keys to the mainland. It includes this long span of bridge.
17. Gotthard Pass, Switzerland
Traveling north from Italy into Switzerland, you’ll come to Gotthard Pass, which you can cross on either the new, straightforward road, or the old roller coaster above. My money’s on the latter.

18. Tichka Pass, Morocco
I recently drove over the 2260m Tichka Pass on my way to Zagora to ride a camel. The pass was cooler. No offense, camel.
19. Pacific Coast Highway, California
This is the only road getting reprised from the original post. It seems to deserve it.
20. Dingle Peninsula, Ireland
The roads of western Ireland are narrow, flanked by green, and sometimes charmed.
