Custome Bridge pathing texture

[Tzalksar]

I need a bridge pathing texture that allows units to pass under it, as well as walk on top of it. I tried removing the pathing all together... it did not work

EDIT: I need it for a TD I'm building, so could it also be possible to build under it, but not on it?

i don't think that such thing is possbile

You can place waygates at each side of the bridge, teleporting units. Just change the effect and it will look somewhat good.
Like duke said, you can't have a bridge that you can walk under.
