Iowa’s Worst Roads to Drive on During a Disaster
By a Well-Traveled Survivalist
There’s a reason most folks underestimate the land between the coasts. From a bird’s-eye view, Iowa looks like a patchwork of cornfields and gravel roads. But when a disaster strikes—be it flood, blizzard, tornado, or grid-down scenario—those roads can turn into a gauntlet. I’ve spent decades traveling through all kinds of terrain, from the jungles of Colombia to the mountain passes of Afghanistan. Let me tell you, Iowa’s backroads in the middle of a Midwestern thunderstorm? Just as dangerous as any warzone.
Disaster has a way of peeling back comfort like bark off a tree. When the sirens start, cell towers fail, and gas stations shut down, your best chance of survival might come down to your wheels and your wits. Below, I’ll lay out 15 survival driving skills every Iowan—or any prepared soul—needs to master, plus 3 DIY hacks to keep moving when your gas tank’s dry. But first, let’s talk about the battleground: Iowa’s most treacherous roads when the world goes sideways.
The Most Treacherous Roads in Iowa During a Disaster
- Highway 20 (Western Segment)
Western Iowa’s stretch of Highway 20 often floods after heavy rains. During a flash flood, this corridor turns into a watery grave. Flatland runoff builds fast, and without elevation to carry it away, you’re driving blind through standing water. - I-80 Between Des Moines and Iowa City
While it’s one of the busiest interstates in Iowa, in a disaster, that’s exactly the problem. It bottlenecks fast, especially in snowstorms or mass evacuations. Don’t count on cruising this route during chaos. - County Road F62 (Marion to Knoxville)
Twisting hills and tree-lined curves make this rural gem beautiful—but deadly. In winter, it becomes a skating rink; in rain, a mudslide risk. No plows, no lights, no help. - Highway 2 (Southern Iowa)
A frequent victim of Missouri River flooding. Entire stretches of this road have been wiped out in past storms. In a bug-out situation, avoid this path unless you’ve recon’d it yourself. - IA-330 Northeast of Des Moines
Tornado alley, plain and simple. The road is exposed, isolated, and flanked by ditches—not where you want to be when twisters tear through. - Gravel Roads in Tama and Poweshiek Counties
During a disaster, GPS will push you onto these gravel roads to “save time.” Don’t fall for it. One storm and they’re impassable. Get stuck here, and you’re a sitting duck.
15 Survival Driving Skills for Disaster Scenarios
- Reading the Road
If the surface looks darker than usual during rain, it’s probably deeper than you think. Water distorts depth. Know how to read the color and ripple. - Driving Without GPS
Memorize paper maps. Practice navigating with a compass and dead reckoning. Satellites fail. Your brain can’t. - Off-Road Maneuvering
Know how to use low gear, lock differentials, and feather the throttle. A field may be your only way out. - Evasive Driving
Practice J-turns and emergency braking in empty lots. If you’re chased or boxed in during civil unrest, you’ll be glad you did. - Tire Change Under Pressure
Be able to change a tire in under 5 minutes with limited visibility. Bonus points if you can do it with a busted jack. - Escape Routines
Know how to escape from a submerged vehicle, including kicking out side windows and cutting seatbelts. Timing is life. - Fuel Conservation Tactics
Learn to coast, hypermile, and minimize gear shifting. Every drop of fuel matters when there’s no refuel in sight. - Navigating by Landmarks
Learn to recognize silos, barns, water towers, and wind turbines as navigational aids. Nature and man-made markers never need batteries. - Communication on the Go
Equip your vehicle with CB radio or GMRS. When cell towers go down, this is your only lifeline. - Driving in Blackout Conditions
Practice using night vision (if you’ve got it) or driving with no lights using only moonlight and memory. Useful when stealth matters. - Handling Panic Situations
Develop muscle memory for when adrenaline spikes. Whether avoiding a downed power line or maneuvering through looters, cool heads drive better. - Improvised Towing
Use ratchet straps, tow ropes, or even paracord to pull another vehicle or debris. Just know the knots and tension limits. - Winter Ice Control
Carry sand, kitty litter, and traction boards. Learn how to rock the car back and forth to break ice grip. - Engine Maintenance
Know how to clean filters, check fluids, and jump a battery with spare wire if you don’t have jumper cables. - Brake Failure Protocol
If your brakes go, pump fast, downshift, and use the emergency brake in pulses—not one hard yank. That saves lives.
3 DIY Survival Driving Hacks When You Run Out of Gas
- The Ethanol Hack
Iowa’s got corn. Lots of it. In an absolute emergency, you can distill ethanol from fermented corn mash. It’s not easy, but with copper tubing, a pressure cooker, and some time, it’s possible. Ethanol burns lean—filter it well or risk engine damage. - The Lawn Mower Siphon Trick
That old lawn mower or ATV in someone’s abandoned shed? Many of them have gas. Carry a siphon hose and a catch can. Be respectful—if it’s not yours, it might be someone else’s lifeline. - Wood Gasifier Retrofit
Advanced, but doable. With steel barrels, wood chips, and basic welding, you can create a wood gasifier to power an older carbureted engine. Think WWII truck tech. It ain’t pretty, but it rolls.
Tips for Staying Alive on Iowa Roads
- Always carry a 72-hour car kit: water, food, wool blanket, trauma gear, jumper cables, flares.
- Keep your gas tank no lower than half full. In a grid-down event, the line at Casey’s stretches to forever—and might never move.
- Scout backroads now—while you still can. Drive them in daylight, mark danger spots on your maps, and cache supplies if you’re bold enough.
When the skies go black and the sirens wail, you won’t rise to the occasion. You’ll fall to the level of your training. So train hard. Know your routes. And never let your tank run dry.
The cornfields of Iowa might look peaceful, but when the world turns upside down, they’ll show you their teeth.
