Some names may have changed, but the all the infrastructure and structures (and berms) are the same. If you overlay this plan to a current satellite image, you can actually see a line of concrete squares and rectangles exactly aligned with the DTD spur, as these are actual buried support footers for monorail pylons.
The spur connecting the MK line with the EPCOT line uses no switches, by the way, so maybe they planned on doing the same type of thing here.
I've been trying to find any evidence of footers poured outside the footprint of EPCOT. They obviously had this plan from the vet beginning, as you can see with the LBV models and schematics. My thinking is that - of they thought of pouring in the pylon footer supports as basic infrastructure built into the park (EPCOT Center), then they must have done the same thing when they built LBV and WDW Village. I just need the evidence!
By the way, I have evidence this was done at EPCOT Center. I have dozens of construction photos that clearly show this!
