They put the Mackinac bridge on there... I have been over it several times....it’s not nearly as bad as the 1000 Islands Bridge. That gem is white knuckles all the way on a good day. Two 12 foot lanes a steep approach and a steel deck, on a snowy day in January with a 30MPH cross wind it will put the fear of god into any atheist.
The wind has blown a couple of cars over the rail of the Mackinaw bridge. Last time I was up there they had the speed limited to 30 mph.
I’ve driven buses over the Mackinac Bridge about 50 times. It’s a bit disconcerting when you think the center of the wheel is taller than the rail. Not really scary though.
