I noticed there is a bug in the scripting of bridges in dungeons. It is really easy to see in Antlion cave..
If you are standing on a bridge and, lets say there is a level below you with a treasure chest or something, if you walk up "off" the bridge, it does not incorporate height. You can just walk onto it. it is as if a bridge is a 4 way connection to any tile around it. It doesnt work on air, but if there is water adjacent to it, or any land you would be able to walk onto, it is accessable.
I do not know if it an be done on ALL bridges, but i noticed it the past 2 times i have been through Antlion cave and Mist Dragons cave.
Just figured I would point it out,
