5 US Highways that May Require a Barf Bag

Even if you don't suffer from car sickness, it's a good idea to have a barf bag or other waterproof receptacle handy when you travel on any of these highways. They're among the steepest, most winding, allegedly haunted or otherwise nausea-inducing roads in the U.S.

1. California State Route 1

You'll miss out on spectacular views of the Pacific Ocean and rocky coastline between Monterey and Big Sur, but because of Highway 1's height and non-stop curves, you might want to close your eyes if you're acrophobic or have a sensitive stomach. (This is not really recommended if you're in the driver's seat.) The good/bad thing is that all the RVs can slow the speed down to about 10 miles per hour, making it much less likely for you to accidentally go careening off a cliff.

2. Colorado State Highway 82

Prepare for a queasy combo of car and altitude sickness on this highway out of Aspen that's 12,100 feet above sea level. There are plenty of sheer drop-offs, sharp switchbacks and, scariest of all, some stretches are even too narrow for two cars to pass each other. There's a reward for surviving this treacherous drive (well, actually it's a punishment for anyone with the slightest fear of heights): crossing the scenic Royal Gorge Bridge 955 feet above the Arkansas River. It's the longest suspension bridge in the United States. Don't look down!

3. Dalton Highway in Alaska

If you've ever watched the TV show "Ice Road Truckers," you know the title refers to Dalton Highway, an isolated road between Fairbanks and Deadhorse that was built for transporting oil to the Trans-Alaska Pipeline. It's still mostly traveled by professional truckers as well as a few brave civilians. For 240 miles, there are no gas stations, restaurants, rest areas or any other places with restrooms. So, along with that barf bag, you might want to bring something to relieve yourself in, or else be prepared to do it roadside on what's often icy terrain.

4. Clinton Road in New Jersey

Wanna see something really scary? Don't forget the barf bag if you're brave enough to take a nighttime drive on this West Millford road that's said to be haunted. Weird stuff like ghosts, UFOs, snow in the summertime, and a mysterious tailgating black truck have been reported. At Dead Man's Curve, if you dare to stop and toss a coin into the water from Ghost Boy Bridge (seriously, I'm not making these names up), the bridge's namesake will either toss the coin back to you or put in the middle of the roadif you believe in spooks.

5. 405 Freeway in Los Angeles

Okay, so it's not at a ridiculously high elevation, twisty-turny or haunted by ghost boys, but the only time traffic actually moves at 65 miles per hour on the 405 through L.A. is in the middle of the nightmaybe. Being stuck in your car for an hour just to make a 10-mile trip is enough to make anyone sick.
