OUR FOREBEARS CROSSED THE OCEAN IN LEAKY SHIPS, AND THE PLAINS IN COVERED WAGONS. Motorists Can’t Face Fears, Get a Lift Across Bridge. “The Mackinac Bridge in Michigan spans five miles and is one of the longest suspension bridges in the world with the roadway soaring more than 200 feet over Lake Michigan. The bridge’s dimensions provide stunning views of the surrounding landscape, but those vistas can be stomach-churning for people with gephyrophobia, or an abnormal fear of crossing bridges. Between 1,200 to 1,400 calls are made every year to the bridge’s Drivers Assistance Program that provides motorists with a crew member to drive them across if they’re too afraid to drive themselves.”
