build me a piece of ice road on top...

build me a piece of ice road on top of nether roof it should have a small soulsand road, 1 block wide, and 2 ice roads just like on a actual road also 1 block wide. The soulsand path should be covered with carpets in the middle of those 2 ice roads. It should NOT be a tunnel with fully covered rood but it should be a messy 6-4 blocks tall walls boulders structure and style (messy not symetric) and it should make a look of deeply designed walls which are not just flat but 3D and structured
