Across the United States, a handful of bridges have earned a reputation so unnerving that some drivers will plan hours of detours just to avoid them. Their fear is not only about height or length, but about narrow lanes, aging steel, fierce winds, and the uneasy sense that one mistake could send a vehicle into open water or a deep canyon. I see these structures as a window into how infrastructure, engineering limits, and human psychology collide on the road.

From coastal spans that sway in storms to mountain crossings that cling to cliffs, these crossings are still vital arteries even as they terrify the people who rely on them. The bridges that most often inspire white knuckles tend to share a few traits: exposed decks, dramatic drop-offs, and a history of closures or accidents that keep anxiety alive long after engineers sign off on safety.

Why some bridges terrify drivers even when engineers say they are safe

Fear of certain bridges usually starts with the physical experience of crossing them, not with a structural report. Long approaches over open water, low guardrails, and narrow lanes can make a driver in a 2024 Ford F-150 or a compact 2018 Honda Civic feel equally vulnerable. When a span rises steeply, curves sharply, or seems to disappear into fog, the brain fills in the gaps with worst-case scenarios, even if the bridge meets every modern standard for load and wind resistance. That gap between how safe a bridge is and how safe it feels is where many of America’s most dreaded crossings live.

Psychologists often point to a mix of acrophobia, claustrophobia, and loss of control to explain why some people freeze on bridges while cruising comfortably on crowded interstates. Drivers who are fine at 70 miles per hour on a straight highway can panic when they see only a low barrier between their car and a 200-foot drop. When a bridge has a well-known history of closures, high-profile crashes, or visible rust and patchwork repairs, that anxiety deepens, even if transportation departments publish regular inspections that rate the structure as sound.

Chesapeake Bay Bridge: a vital link that feels like open water

Few crossings inspire more dread than the Chesapeake Bay Bridge in Maryland, a pair of spans that stretch roughly 4.3 miles across the bay and rise high enough to let large ships pass beneath. For drivers who dislike bridges, the combination of length, height, and exposure can feel overwhelming, especially when strong crosswinds push against tall vehicles or thunderstorms roll in from the Atlantic. I have seen people describe gripping the wheel so tightly their hands hurt by the time they reach the other side, even though the bridge is a routine commuter route for thousands of residents.

The fear has grown into a cottage industry. Some local companies offer paid “drive-over” services where a professional driver takes your car across while you ride as a passenger, a business model that exists almost entirely because of this one bridge’s reputation. Transportation officials have periodically restricted certain vehicles during high winds and have invested in maintenance and inspections to keep the aging spans in service, but the psychological barrier remains. For many, the Chesapeake crossing is not just a piece of infrastructure, it is a test of nerve that they would rather outsource or avoid entirely. Unverified based on available sources.

Mackinac Bridge: engineering marvel, anxiety machine

In Michigan, the Mackinac Bridge connects the Upper and Lower Peninsulas with a suspension span that runs about 5 miles across the Straits of Mackinac. Its steel grating in the center lanes, designed to reduce wind pressure, creates a humming vibration under the tires that some drivers find deeply unsettling. The bridge’s towers rise more than 500 feet above the water, and the roadway itself sits roughly 200 feet above the straits, a scale that can make even a confident driver feel exposed when gusts sweep in from Lake Michigan and Lake Huron.

State officials have long emphasized that the Mackinac Bridge is rigorously inspected and maintained, with lane closures and speed restrictions during severe weather to keep traffic safe. Yet the bridge authority also acknowledges driver fear by offering an escort service where staff will drive a vehicle across for those who request it. That dual reality, a structure that is both a carefully monitored lifeline and a place where people routinely freeze or pull over in panic, captures why the Mackinac ranks so high on lists of crossings that people would rather never face again.

Delaware Memorial and Sunshine Skyway: high-speed fear on coastal corridors

On the busy Northeast corridor, the twin spans of the Delaware Memorial Bridge carry Interstate 295 and U.S. Route 40 over the Delaware River between Delaware and New Jersey. The bridges’ tall steel arches and relatively narrow lanes, combined with heavy truck traffic, create a sense of compression that can rattle drivers who already dislike heights. When crosswinds hit or rain reduces visibility, the feeling of being boxed in between tractor-trailers and low barriers can be intense, even though the structure is a critical freight and commuter route that operates around the clock.

Farther south, Florida’s Sunshine Skyway Bridge over Tampa Bay adds another layer of psychological weight because of its history. The current cable-stayed span opened after a freighter collision in 1980 caused a section of the older bridge to collapse, sending vehicles into the water and killing 35 people. That tragedy still shapes how some drivers view the modern Skyway, even though it was designed with wider shipping channels, stronger piers, and extensive safety upgrades. The soaring central span, which rises more than 190 feet above the bay, offers sweeping views that tourists love, but for those who know the history, every crossing can feel like a reminder of what went wrong on the previous structure.

Verrückt-style memories and the legacy of structural failure

Even when a bridge has no major disaster in its own past, memories of other structural failures can color how people experience it. The collapse of the original Tacoma Narrows Bridge in 1940, captured on film as the roadway twisted violently in the wind, remains one of the most widely shared engineering cautionary tales in the world. Modern suspension and cable-stayed bridges are designed with far more sophisticated wind modeling and damping systems, but the image of a roadway buckling like a ribbon still surfaces whenever a long span sways underfoot.

That history matters because fear is rarely rational or neatly contained. When drivers approach a long, exposed crossing, they may subconsciously connect it to every viral video of a collapsing structure or every headline about aging infrastructure, even if the bridge in front of them has passed its latest inspection with room to spare. I find that this blend of personal anxiety and collective memory helps explain why some spans become notorious while others of similar size and age do not. The story is not only about steel and concrete, it is about what people bring with them when they roll onto the deck and look down at the water or the canyon below.
