1. Has any one ever used real stone for rock face? I just remove an old soap stone sink from the basement and after they took it away I was looking at the small fragments left, they were flat on one side and the perfect rough rock face on the other! But, its all gone now:curse: I just finished the double track bridge across the "Rock facless canyon" and found that one side was lower than the other. So I need a slope on the right side to meet the track on the other side. I did not make the bridge level. It is about 1/8" lower on one side to help reduce the slope on the other side. 2. Is this done, that is build bridges on a slope? It is hard to see the slope so I think it looks ok.
