Is This Route in North Dakota the Longest Straight Road in America?
When planning a road trip, you might scope out the route with the most roadside attractions or the prettiest scenery—or, if you're interested in activating cruise control and giving your feet a break, you might look for something straight. According to Ken Jennings, writing for Condé Nast Traveler, North Dakota claims to be home to the longest straight road in the country.
State Highway 46 covers 124 miles of Midwestern prairie between the communities of Streeter and Lithia. A quick glance at a map suggests that the road does unfold in a straight line as advertised, but closer examination reveals that its status is more complicated than North Dakota would like to admit. There are places where highway 46 diverges off its narrow path slightly, like the spot where it runs over the Sheyenne River, for example. If you're sticking to the strictest definition of the word "straight," 40 unbroken miles of the highway is the longest stretch that qualifies.
Forty miles of driving in the same exact direction is impressive, but for an even smoother ride you'll need to travel west to Utah. There you'll find a 30-mile section of Interstate 80 that crosses the Bonneville Salt Flats. Not only is this route straight, it also falls along one of the flattest spots in the country.
Of course, not every road tripper is looking for the route that takes the least effort to drive. Roads with insane hairpin turns built in treacherous locations aren't hard to find if you know where to look.
