They are in the process of re-routing the road now. It looks like the road will turn into the old parking lot right next to Mister Hydes, go about 100 yards or so, then turn back out to RT 43.
Looks like X-Flight will sit right next to Supe in the front corner of the parking lot. They may open up the utility entrance next to Hydes with a walkway to access the new ride.
I think once they secure this new area of the park, construction will begin. They were putting in what appeared to be fence post when I was by there on Sunday.
