You can have a bride, and you can have an underpass, but you can't have both a bridge and an underpass. See what I mean? In other words, you can have a bridge, but not be able to go under it. You can have an underpass, but not be able to go over it. There is only one layer of mesh, and you can't overlap any part of it over itself.
With some really tricky scripting, you can possibly make a bridge that will allow you to go over if nobody's under it, and allow you to go under it if nobody's on it. There is something like this on the last level of Myth II.
