Road trips are a uniquely US pastime, making it easy to enjoy the breathtaking beauty of the country’s landscape. Highways are not only a convenient way to see gorgeous sites like the Arizona desert or the stunning glory of the Maine coastline, but they also power the American economy by enabling intercontinental freight. However, National Highway Traffic Safety Administration (NHTSA) data shows that 40,990 died in fatal crashes in 2023, highlighting the serious risk of interstate travel. Heavy traffic, unforgiving terrain, and poor infrastructure all contribute to high fatalities along America’s most dangerous highways.
Today, we’ll explore the most dangerous highways, interstates, and expressways in the US, infamous for their many fatalities, and then discuss how you can protect yourself and your loved ones if you are injured in a wreck.
US Highway 1, Florida
US Highway 1 starts in Key West, Florida, and passes along the East Coast, including South Carolina, Rhode Island, and New York. It terminates at the US-Canadian border in Fort Kent, Maine, making it the longest north-south highway in the US. Along the way, it passes by important towns like Daytona Beach, Florida; Augusta, Georgia; and Richmond, Virginia.
However, US 1 also has a reputation for fatal crashes, making it one of America’s most dangerous highways. The most perilous section is the Overseas Highway, which connects Miami to Key West. This dangerous highway is known for its limited infrastructure and terrifying ocean currents. Many grow so anxious that they need police assistance, even without a crash.
AAA calculated that 87 people lost their lives along US 1 from 2015 to 2019, highlighting the significant risk involved in using this convenient passage.
Interstate 45, Texas
I-45 is a crucial route through Texas, passing through Dallas, Houston, and Galveston. Despite being relatively short, it is one of the most dangerous highways in America. Budget Direct, an Australian insurance company, named it the deadliest road in the US.
This road passes mostly through heavily congested urban areas, and its complicated network of interchanges can make it hard to find the right exit, especially for tourists. Certain areas of the road are also very outdated, with faded signage and markers, increasing the risk for those attempting to find the right off-ramp.
According to fleet manager Teletrac Navman, 260 people have died in fatal crashes along I-45 from 2016 to 2019. While this highway may only serve Texas, it’s one of America’s most dangerous highways and should be avoided at all costs.
Interstate 40, North Carolina and Tennessee
I-40 cuts across the US, from California to North Carolina. It passes by beautiful sites like the Mojave National Preserve along the way, making it popular with roadtrippers. However, many fatal crashes occur here, with about 9.89 deaths per 100 miles.
The Pigeon River Gorge section of I-40 straddles the border of North Carolina and Tennessee. It’s known as a particularly dangerous area due to frequent mudslides and steep descents. Like many roads in the Appalachian Mountains, it was blasted into mountain passes, but poor road maintenance has made these passages extremely difficult to navigate, especially in poor weather.
State Road 138, California
State Road 138 has a beautiful nickname: Pearlblossom Highway. Unfortunately, locals also know it as “Blood Alley” due to the many fatal crashes that have occurred there.
In many places, SR-138 has only two lanes and cuts through steep, mountainous terrain. Combined with high speed limits, poor road conditions, and heavy commercial traffic, it’s no wonder that Pearlblossom Highway sees dozens of serious accidents yearly.
The deadliest stretch of SR-138 is where it intersects with Interstate 15 near the Cajon Pass in San Bernadino County. I-15, which passes through California, Nevada, Utah, Idaho, and Montana, is equally perilous, but tragedy strikes when these two collide in a tight mountain pass. This section sees approximately 13 deaths per year.
Interstate 10, Arizona
I-10, which starts in Santa Monica, California, and extends to Jacksonville, Florida, is a crucial interstate artery that sees heavy traffic, especially from commercial vehicles. It passes across wildly varying terrain, including mountains, deserts, prairies, and swamps, which requires drivers to remain alert for different weather conditions.
The most dangerous highway section is in Arizona, where long stretches of monotonous desert can encourage people to speed or even fall asleep at the wheel. Extreme heat, dust storms, and sudden downpours can push both vehicles and drivers to their limits, especially in the sizzling summer months.
Even worse, about a third of fatal crashes on this highway involved alcohol, which can put even the most cautious motorist at extreme risk. According to Fox Weather, almost 500 people were killed along Arizona’s I-10 in a six-year period.
James Dalton Highway, Alaska
The James Dalton Highway was constructed in 1974 to transport freight from Fairbanks to Deadhorse. It cuts through some of the deadliest terrain in all 50 states. While steep grades and perilous bridges over the Yukon River are present, the real problem with this highway is its remoteness.
There are only three towns along the entire 414-mile route, including one 240-mile stretch with no gas stations, rest stops, or other amenities. Worse still, cell service can be spotty, meaning there’s no one to help you if your vehicle is disabled or run off the road.
Some portions are entirely unpaved, and Alaska’s brutal winters don’t make it any easier. In fact, the Bureau of Land Management discourages anyone from traveling from October to April, with February and March being the deadliest months.
Million Dollar Highway, Colorado
This dangerous road got its nickname from an earlier traveler who claimed she’d need to be paid a million dollars before she took this route again.
While the Million Dollar Highway is absolutely gorgeous, winding through Colorado’s mountainous regions and reaching up to 11,000 feet above sea level, it’s also notorious for its sharp turns and harsh weather. The Durango Herald reports that there is an average of 7 deaths per year on this road.
Approximately 400 people have passed away here since 1992. In some cases, it’s not even due to careless driving or speeding: several people have been killed by avalanches and mudslides along the way.
Stevenson Expressway, Illinois
While Illinois’ catchphrase may be “Mile after Magnificent Mile,” the Stevenson Expressway has developed a reputation that is anything but magnificent. A staggering 88% of traffic deaths in Chicago are linked to reckless or egregious driving behaviors, and this Chicagoland expressway represents the worst of the worst.
Several fatal crashes have been linked to road rage on the Stevenson Expressway, including shootouts and drag racing. In July 2024, there were two separate shootings along the Stevenson in one day, which entirely closed down all inbound lanes and led to severe congestion. Two people died, and one person was injured in these separate shootings.
Of course, drivers also have to contend with Chicago’s horrible winter weather on this dangerous highway. In one horrific case, a speeding driver lost control of their car on the expressway and slammed through a concrete barrier, plunging 43 feet off the expressway and to the road below. Two were killed in the crash, while two others suffered life-threatening injuries.
Interstate 285, Georgia
Nicknamed the “Perimeter,” I-285 encompasses Atlanta in a loop and connects to all other major highways in the state. While this is convenient, it also leads to heavy traffic and many merging points, making it harder to avoid crashes.
The Perimeter’s circular design also means that there are constant sharp turns, which can cause many drivers to miscalculate their speed. Because many commercial trucks use the road, the signage is not very clear, and drivers may try to quickly cut across multiple lanes of traffic to reach their exit.
A 2015 story from Vox magazine reported that there were 3.5 deaths per 10 miles of road on I-285, making it the deadliest highway in the country at the time.
What to Do After a Car Accident
It’s crucial to contact the police and get medical assistance after an accident, as you may have serious injuries that are not immediately apparent. Get contact information from others involved in the crash and ask for a copy of the police report, which your insurance company will need when you file a claim.
You should always contact a lawyer for a free consultation after a serious accident. They can guide you through the insurance claim process and negotiate with the agency on your behalf to ensure that you get maximum compensation. These law firms will have resources unavailable to the average person, including expert witnesses and accident reconstruction teams.
Driving on America’s most dangerous highways can be a terrifying experience, but defensive driving can help you avoid a fatal crash. Stay alert, don’t drive drunk or tired, and never use your phone while driving. While some accidents are unavoidable, you can rely on skilled personal injury experts to advocate for you in the event of a serious crash.
