let me rephrase - 3 interchanges - no expectation of Fed/State funding
but developers involved in potentially funding one or more of them.

Is there a FHWA site that goes through rhyme and verse of how these
studies are done?

We have been through all kinds of scenarios at our District for Access
Justification reports, from strictly developer-driven to governmental
economic development-driven to system interchange-driven (as in a new
interstate-to-interstate connection).  In addition, an AJR is required
when an existing interchange is upgraded with a non-conventional
design such as a SPUI, which we have in the works at one location.
Expect about 40 pages of document and about 150-250 pages of
appendices unless there is a lot of complexity to the location.  If
you need a link to look at a sample AJR, there's a lot of them out
there on-line.  As far as doing an AJR to attract funding, it's a
necessary piece of the puzzle, but gets you maybe 5% of the way there,
in my experience.

Here's a link to one that was approved in our District.

very good. thank you.

one more - how long does one of these critters normally take to do
and how long after they are done are they considered useful enough not
to have to do another one or an update?
