Footers being built already. Basically confirming steel coaster... No RMC after all. But a sleuth on reddit (thanks, scott m) found this statement from an individual in the KW community.
Heard some juicy news from my Kennywood source today. The 2019 coaster is supposedly an Intamin multi-launch coaster that will utilize the hillside, ravine, and former railroad building just like the original RMC plan was supposed to. RMC plan was scrapped due to different stability requirements for terrain for wooden and steel structures. Project is supposed to be the park’s biggest investment to date. One of the two launches will be inside of the railroad shed. Unclear at this time where the other launch is but there will be several inversions similar to Maverick at Cedar Point and Cheetah Hunt at BGT .
I wouldn't put TOO
much weight into this just yet, but things are certainly heating up. At least the 2019 coaster is pretty much confirmed!
