There was a workaround. With ladders - also semi vertical / horizontal/ diagonal - you can pass normally unpassable terrain. I already was thinking if it wasn't possible to create invisible horizontal ladders with walking animation instead. Or my personal favorite would be an invisible make leap object, which would work like a ladder but instead performing thr leap animation.
This way wouldnt be able to stop under your bridge but have to watch the animation until character arrives again in the green walkable area.
Just as an idea. Maybe try with a horizontal ladder first,, probably it will be messy and charcacter will climb up an invisible wall to your bridge instead of surpassing it . But maybe fiddle around a bit and you might be successful.
