Bridges, Evil evil Bridges

I'm having a lot of trouble placing bridges in my map. It seems that no matter how I have them placed, they are always really high out of the water in-game. They look fine in world editor, but then the game goes and shoves them up really high. Any help on placing bridges is appreciated. :D

Use Ctrl + PageUp and PageDown to move doodads up and down.

Then play around with trial and error till you units can walk over it.

Thanks Iron_Iran. I never knew you could do that.
