It's behind eastern Main Street. It's the bypass and Tomorrowland Terrace can be seen to the right.
This is from Disneyland, but it could be useful to understand what they're doing with the similar Backstage Alley at MK. The new Backstage Alley at Disneyland opened this weekend and follows an identical path behind Main Street USA as the one in Magic Kingdom.
It's entered via a new building off of the Town Square (that replaced an unused patio), a new "Livery Stables" that has big barn doors that stay closed 98% of the time but are opened on the busiest days that lead directly into the new alleyway that parallels Main Street USA.
This is directly north of where Tony's Town Square Restaurant is at MK.
Thru the barn doors with the other "cattle", you go into the alley itself. It's very plain, but not unattractive. A basic wide alley, with clapboard walls with framed Attraction Posters and some flower boxes (that hide music speakers), with lattice work arches overhead and some tall trees on the other side of the walls to block views of fireworks and some "backstage" buildings. Simple globe light fixtures and popcorn lights on the arches will provide lighting, as this alley will primarily be used at night after fireworks and Fantasmic!.
The alley dumps you out at the backside of Main Street right into The Hub, in a reworked area with a new First Aid building and redesigned planters and walkways ready to guide crowds into the alley when needed.
What might the similarities be between this brand new Disneyland Backstage Alley and the Magic Kingdom version yet to open?
