When I was a child, I used to have a big fear of crossing bridges. Every time I was in a car that was about to go over a bridge, I would close my eyes or cover my face until we reached the end of the bridge.
I don't know exactly where that fear came from, because I didn't have it earlier. But one day, I just started getting a little anxious every time I saw a bridge come into view and realized that whatever vehicle I was in was going to be getting on it.
Over the years, that fear has decreased quite a bit, but I still prefer to get over a bridge as quickly as possible.
