Gephyrophobia is the weird word used to describe a fear of bridges. You might think that it's just a simple fear of heights, but it's actually way more complicated. Psychologists who have researched this phobia have come to the conclusion that it's more about the lack of control and other factors, stimulating anxiety and panic than it is just being up in the air. That's one reason many sufferers find their symptoms worsened when they hear about bridge disasters. As a result of this condition, a rather unusual business has popped up. Bridge-crossing services exist for several spans throughout the country, including the Mackinac Bridge in Michigan and the Chesapeake Bay Bridge featured in this Inside Edition video clip. By calling in advance, a driver will meet you near the bridge and take over for you, easing some anxiety, especially since no harm will come to you if you do happen to panic on the roadway.
