I also don't think Rookburgh will feature rockwork (which should hopefully be a refreshing change in style after some rockwork heavy areas recently) but Universal Rocks could be/most likely are doing the brickwork facades of steampunk buildings etc.I don't see how Rookburgh will have a lot of rockwork due to the Steampunk theme but maybe they'll be doing more work in the Black Mamba/Mexico area?
This was my first thought. The curved side for the screen seems to be lined up with and close to the track.Maybe they use the screen for the darkride portion ?
*Cough*TempleoftheNighthawk*Cough*It's wonderful to see a park going to these lengths to keep their older attractions up to the standard. They really care and it's awesome to see.
