My mom will get out of the car,trade with whoever is in the passenger side at the beginning of the bridge, make someone else drive over it, then on the other side she gets back in the drivers side and drives the rest of the way. She HATES bridges too.
I think she's the culprit of my fear of driving between two sides of water. Atlantic City is famous for having roads that have no guard rails and have water on both sides. Hate it!!!
