That's something new, but more on that after this...
I brought that up because I wrote a big post here a few months back speculating that there were big plans for DTD that included parking garages, an I-4 ramp, and monorail expansion. So far, just the DTD expansion and the garages I speculated about were accurate predictions, but those predictions were based on my suspicion of an overall secret Master Plan to expand the monorail system. Everything is tied together and, in that post, I made clear why one element needs another to make it all work. I was talking about infrastructure in the LBV area. I showed concept art and pictures of models that showed monorail and a peoplemover system in the area. I focused on a planned route from EPCOT to LBV. I can prove that infrastructure for that route was buried along its right of way through the EPCOT Center construction zone. In the LBV area, all I have are the pictures of models and art renderings. I theorized that a parking structure at DTD (and connected I-4 direct off-ramp) would help support a monorail route going to EPCOT.
Now, back to what you said. I didn't know about that. I know about the footers in EPCOT for the LBV route that were buried in the early 80's. I suspect there must be footers also in LBV, but can't find any evidence other than early plans and models. Please tell me everything you know about the ones buried in the 90's, so I can include that in my investigation...
