Fear of Crossing Bridges

Gephyrophobia

About a thousand drivers a year hand their keys to somebody at the Mackinac Bridge, which connects Michigan's two peninsulas, and are driven across for a small fee. The Mackinac Bridge Authority runs the service as a routine part of its operation. It is the largest piece of hard evidence attached to gephyrophobia, and it did not come from a study.

How the bridge authorities responded

The New York State Thruway Authority ran the same service on the Tappan Zee Bridge, and as of 2008 was performing it about six times a year. The Maryland Transportation Authority offered one for the Chesapeake Bay Bridge and has since handed the role to private companies.

Set the Mackinac figure against the Tappan Zee figure and something becomes visible that no article states. A thousand a year against six a year is not a difference in how many frightened drivers exist in Michigan and New York. It is a difference in what each bridge is like to cross, and the Mackinac has open steel grating in its span.

Why the word covers tunnels as well

The term covers bridges and tunnels alike, and older structures more than new ones, which is a specific claim about what is being read. Somebody frightened of a bridge is reading it for signs of failure.

The three fears the material names are separable:

  • driving off the bridge, which is about control
  • a gust blowing the vehicle off, which is about force from outside
  • the bridge collapsing, which is about structural integrity

Only the third is a fear of the bridge itself. The fear is stronger on taller bridges, which is where it overlaps with acrophobia.

What a clinician says it actually is

Michael Liebowitz, who founded the Anxiety Disorders Clinic at the New York State Psychiatric Institute, is quoted directly and is worth quoting in full, because he declines to treat this as a phobia of bridges:

It's not an isolated phobia, but usually part of a larger constellation ... It's people who get panic attacks. You get light-headed, dizzy; your heart races. You become afraid that you'll feel trapped.

That reading puts gephyrophobia inside panic disorder and makes the bridge a setting rather than an object. A bridge is a stretch of road with no exits and no way to stop, which is a description of a place where a panic attack cannot be escaped rather than a description of a hazard.

What the Mackinac death actually shows

One death is attached to this fear in the record and the attachment is doubtful. Leslie Ann Pluhar's Yugo went off the Mackinac Bridge in 1989. The subsequent investigation concluded that she had stopped over the open steel grating of the span and that a gust blowing up through the grating pushed the car off.

The material notes, flatly, that the recorded wind speeds on and around the bridge at the time do not support that conclusion. The story is nevertheless the one that circulates, and it is the concrete image behind one of the three fears named above. A fear that a gust will blow a car off a bridge has one famous case, and the case does not carry the explanation attached to it.

Where gephyrophobia turns up

The cultural record is unusually dense for a term with no literature. Lucy invokes it, with a slight mispronunciation, at her psychiatric help stand in A Charlie Brown Christmas in 1965. Michael Palin's character Jim Nelson has it in the 1991 Channel 4 drama G.B.H. Brick has it in the episode of The Middle titled The Bridge. Frank Heffley has it in the Diary of a Wimpy Kid book The Long Haul, becoming dizzy in stopped traffic on a bridge.

Four appearances across sixty years, and the fear has been treated as comic in most of them.

Why the evidence is operational rather than clinical

No prevalence figure exists. The 2008 printed encyclopedia of phobias defines the word in three words and cross-references itself. The evidence that this fear is real and reasonably common is entirely operational: bridge authorities in three states found it worth staffing a service for, and one of them is still running it a thousand times a year.

Common questions

Questions about Gephyrophobia

Can somebody else drive a car across a bridge?
On some bridges, yes, and it is a routine service rather than a favour. The Mackinac Bridge Authority drives roughly a thousand cars a year across for a nominal fee. The New York State Thruway Authority did the same on the Tappan Zee about six times a year as of 2008, and the Maryland Transportation Authority's Chesapeake Bay Bridge service is now run by private companies.
Why does one bridge need a thousand crossings a year and another six?
Nothing in the material explains it, and the gap is too large to be about population. The likeliest reading is that it is a fact about the bridges rather than the drivers: the Mackinac span has open steel grating, through which the water is visible while driving.
Is it fear of the bridge or fear of panicking?
Michael Liebowitz, who founded the Anxiety Disorders Clinic at the New York State Psychiatric Institute, says the latter. He describes it as not an isolated phobia but part of a larger constellation in people who have panic attacks, and names the specific fear as becoming trapped. A bridge has no exits and nowhere to stop.
What happened on the Mackinac Bridge in 1989?
Leslie Ann Pluhar's car went off the span. The investigation concluded she had stopped over the open steel grating and that a gust blowing up through it pushed the vehicle off. The recorded wind speeds on and around the bridge at the time do not support that conclusion, which the source states plainly, and the story circulates anyway.
Does the fear cover tunnels too?
The source defines gephyrophobia as the fear of bridges and tunnels together, especially older ones. That is unusual: most phobia words name one object. What the two share is that both commit a driver to a stretch of road that cannot be left partway.
