The technical issue from the beginning with that has always been that you can’t have a grade crossing of an automated guideway technology with something that isn’t. For traditional steel rail-based systems that’s a technical issue, but for the current Skyway technology that’s a physical issue, because the beam physically cannot be crossed at grade level. As Lake has said before, the San Marco extension is probably feasible if one can get the beam under I-95 and then over or next to the FEC where it can then travel at grade to a station, but anything else would run into problems.
Given what we’ve seen and learned the last 7 years and the funding we know is available or could be made available it seems there are two broad courses of action that could be taken at this point if we choose to abort the U2C program in its current form:
- Modernize the existing Skyway with a standard technology and reexamine the preferred expansion alternatives. The ideal option would be figuring out as fast as possible how to convert the system to Miami’s standards to enable a larger joint order for vehicles and systems. Once that’s underway, decide independently whether to expand it as an elevated system for big things like the stadium district or perhaps as more of a Lymmo-style shuttle for things like the hospitals. Places in Asia have managed to run these as effectively full metro systems before so maybe the goal should move in that direction long-term. This fits the original mandate of “Keep, Modernize, Expand.”
- Commit to running the Skyway until it physically cannot go on for operational or safety reasons, but in the meantime develop the plans to tear it down, payback any remaining federal obligations if required (but lobby via our legislative delegation for that to be reconsidered in light of the DPM program overall), and plan a new mass transit system without the burden of the Skyway legacy (but perhaps reuses its alignment if ideal).
There's a third option that most people ignore because of continued attempts to make the Skyway and its infrastructure something it was never intended to be. The system is a downtown circulator. It doesn't serve the same role as everything else (LRT, streetcar, heavy rail, etc.) people compare it with, and it was never intended to do it. Unfortunately, what JTA wants to do is costing taxpayers just as much as those other systems, without the benefits that come with them.
The third option is to upgrade and maintain the Skyway as is
(the first option you mentioned) and focus on a different system altogether that plays the role that system is supposed to play. That system can link with the Skyway at the JRTC and those who want to get to DT stops will have to transfer to the Skyway, in the same way that its Miami Metromover sibling plays with Metrorail.
With this scenario, we don't owe the FTA a dime and we can spend our local money on getting a more extensive, complimentary transit project off the ground. Some don't like the idea of transferring between different modes but that's a reality with every major city's public transit network.
