Renee Crays hunched forward in the rear seat of her pickup. One hand clutched the headrest of the seat before her so tightly that her knuckles turned white.
The Mackinac Bridge's vertical suspension cables flowed past her window as the truck climbed the gentle slope toward the center span on a recent sunny, beautiful day.
Gulls soared about the bridge towers. A freighter lumbered in the distance. But Crays showed no interest in the panoramic view. She didn't glance out the side windows at all, only straight ahead, tense.
"I'm scared to death of this bridge," she said. "It makes me sick to my stomach. It makes me dizzy."
In the driver's seat, John Lane nodded at the rearview mirror and offered a reassuring smile. In three years working with the Mackinac Bridge Authority, he's chauffeured hundreds of people over the bridge who, like Crays, were too nervous to drive themselves.
A nurse from Sault Ste. Marie with family in Cheboygan, Crays is a regular user of the Bridge Authority Driver Assistance Program. Every time she makes the trip to visit relatives she asks for help. Lane has driven her several times.
"This service is wonderful," she said. "I never have to wait more than 15 minutes. And they always do what I ask: They stay in the middle, away from the edge."
Bridge Authority workers deal with gephyrophobia - gephyra is Greek for bridge - every day. More than 500 nervous drivers have handed over their keys so far this year. Last year, 1,085 were chauffeured over.
Some people call or e-mail in advance to arrange for a driver. Others, generally first-timers, approach the bridge and note the drop - 199 feet - from the road to the whitecaps below. They study the tensile thinness of the suspension cables and decide they can't drive it.
Fearful drivers ask for help at the toll plaza on the St. Ignace side or at a designated Bridge Authority phone hut on the Mackinaw City side. A few minutes later a worker comes to the rescue, assuming the driver is willing to sign a waiver stating they're insured and their vehicle isn't stolen.
Bridge Authority employee Mike Buby has driven many people and understands their fear. "You've never been to Michigan, never seen the bridge, and there's a west wind blowing 30 miles an hour," he said. "We've had people that go under a blanket."
Waiting for the Edmund Fitzgerald to sail by.
The lack of paving is for wind flow.
It's also one of the most beautiful bridges in the world.
My sister suffers from this, and I feel it to some degree too, especially when on my motorcycle.....
Never drive a Yugo over the Mackinac Bridge..

It's high, but isn't the bridge in Dover Delaware higher above the water?
My wife has a thing about big bridges although she maintained pretty well when we drove across this one. Personally, I'd have a problem walking over it when you can see through to the water; I'd need something to hang onto (or else be pretty drunk.)
I love going over that bridge. The skyway into Chicago is pretty cool too...I drove that once at 11pm...the steel mills were fired up and I was blasting "One" by Metallica on the cd player
I sincerely thought I was driving into hell.
"Waiting for the Edmund Fitzgerald to sail by."
I don't the the Edmund Fitzgerald ever sailed under the bridge. It always traveled between Cleveland and Duluth.
Makes sense. Every time I'm there, even if calm on the approaches, the wind is whipping pretty hard on the brige itself. And there's got to be some venturi effect based on the narrowness of the straits at that point.
While I am not surprised the AP is running a story about a poor pityful person and their personal problems about crossing a silly bridge - I was surprised they did not work in how this persons problem was Bush's fault.
I don't believe the Edmund Fitzgerald ever sailed anywhere!
You know the history of the waitress gone missing when her Yugo went over the side?

Hi yooper, you're a long way from home. Didn't know that about the Fitzgerald. But I have heard that
"they'd have made Whitefish Bay; If they'd fifteen more miles behind her."
The Big Mack is a beautiful bridge. I think a lot of people get vertigo because the landscape is so open . . . so BIG. And then there's the aforementioned grille in the road! ;-) It's been years since we drove across it, but it's definitely a gorgeous sight.
Another favorite is that bridge in Tampa Bay. The coast one one side and the gulf on the other make for a wonderful drive.
