Some of America’s most famous roads are remembered for more than just beautiful scenery. Behind every sharp turn, isolated stretch, or engineering marvel is a story that sounds almost too unbelievable to be true.
1. The Overseas Highway Was Built on a Railroad That Was Destroyed by a Hurricane
Driving from mainland Florida to Key West feels like cruising across the open ocean. What many travelers don’t realize is that much of the route follows the path of Henry Flagler’s Overseas Railroad, which was devastated by the powerful Labor Day Hurricane of 1935 before sections were rebuilt into the highway used today.
2. The Million Dollar Highway Earned Its Name for Several Different Reasons
Colorado’s Million Dollar Highway has no guardrails along many of its steep mountain curves. Some say it cost a million dollars per mile to build, while others claim the fill dirt contains gold ore worth even more.
3. The Dalton Highway Exists Because of an Oil Pipeline
Stretching more than 400 miles through Alaska’s wilderness, the Dalton Highway was built to support construction of the Trans-Alaska Pipeline. Today, drivers can travel for hours without seeing a town, gas station, or cell service.
4. Tail of the Dragon Has More Than 300 Curves in Just 11 Miles
On the Tennessee-North Carolina border, this winding mountain road has become legendary among motorcycle riders and sports car enthusiasts. There are no intersections or driveways, just one sharp curve after another.
5. Going-to-the-Sun Road Took More Than a Decade to Complete
Cut directly into the mountains of Glacier National Park, Montana, this engineering achievement required workers to carve narrow ledges into steep cliffs while battling heavy snow and short construction seasons.
6. The Blue Ridge Parkway Was Designed for the Journey, Not the Destination
Unlike most highways, the Blue Ridge Parkway was built to encourage slow driving. Commercial traffic is largely absent, allowing travelers to focus on overlooks, forests, and mountain scenery instead of getting somewhere quickly.
