Universal has published documents outlining the bidding process for a potential transportation network linking its new Epic Universe park to the broader Universal Orlando Resort, according to the Orlando Business Journal.
This follows rumours of a collaboration with Elon Musk’s tunnel construction firm, The Boring Company, to develop an underground transit system.
The other two parks and resorts they want to connect to are landlocked by other urban development. My guess is Universal built as close as they could with regard to what land was available for the initial new park and future expansion plans.
