I found the missing bridges that everyone has been saying were missing.
They're in Des Moines, Iowa. I was just flying around there for no
particular reason and on the river there's no less than 4 bridges not more
than a few hundred yards from each other. Then to top it off there's another
bridge about a mile further.

For the people who said that there aren't any bridges, we now know the true
story. Iowa actually bought them, then disassembled and rebuilt them in Des
Moines!

Oh, on a trip from Chesapeak Bay, MD to Baltimore I saw a bridge that was
actually crossing a river, but unfortunately all the cars that needed to use
it had to be part boat, part 4x4 because the entrance/exit was in the river.
D'OH!
