I was just thinking about how SW8 will be accessed during construction. To me, the most obvious location at the moment would be using the KC path.
There is an access point which leads to another path (which runs behind the SW8 proposed ride location to the haunted hollow entrance) and the old lake area. From this area, it's only a short distance to the nearest gate which leads off the park.
I'm thinking this would be used during the main season since there is no other way to access the ride, other than the path that runs behind CRR and ends at the start of haunted hollow. (this would require it to run straight through gloomy wood).
This also probably explains why there's a maintenance building being built behind duel, since that path can be used.
