This is my suggestion for a redstone bridge.
Now some of you may think this won't be so immersive because an opening-and closing bridge will be too overcomplicated and will not fit in to the theme of minecraft.
Truth is, that is not what I'm suggesting at all.
What I am suggesting is a small bridge that can go across redstone. So you can put redstone over redstone, making it possible to compact redstone much more and even create 2-layer circuits.

If any of you find this idea interesting, then please feel free to support! If you don't like it then explain why.
That's all from me, bye.
