Muchas gracias por su respuesta.

There is a great deal of material regarding several aspects of Roosevelt Island planning and redevelopment, so here are three aspects and websites to start. 

Historically used for hospitals, redevelopment started with a in the 1970s based on a plan,including affordable housing, by Johnson and Burgee for New York State Urban Development Corporation. Several "towns" built in multiple phases since then, involving other noted architects, J.L Sert, Gruzen/Samton. The original Octagon House was rehabilitated in 2012.  A tram provides access to Manhattan as well as the RFK Bridge auto connection to Queens.  Roughly 12,000 people now live on the island, and there are numerous retail stores, parks and other amenities.

Louis Kahn designed Four Freedoms Park commemorating FDRoosevelt was finally completed in 2012 at the southern tip of the island.

In 2008, NYC Mayor Bloomberg held a competition for a new technology education facility, won by Cornell and Technion, and Roosevelt Island was selected as the location.  The plan was prepared by SOM and James Cormer,, now the first phase of an academic building and housing are under construction.  https://tech.cornell.edu/future-campus

What interest me the moast on the Roosevelt Island are streets - as Peter Blake, in his book Form Follows Fiasco (1977)   writes: But the new Rooslvelt Island is distinguished from most other New Towns built in the United States since WWII by one small and seemingly obvious feature - it has a real street....etc.  On the same page he writes abut Split II,: Split III is a city of streets - a city of pedestrian streets, densly popilated, lined with stores, more or less devoid of cars...etc.  I live in Split and I am taking it as a case study, as well as the Roosevelt island 

The streets in Split have much more history and character, and both partial cause and beneficiary of Split becoming a tourist destination.  Main Street on Roosevelt Island is rather drab, but not quite fiasco, serves local needs.  With new apartments and campus being built, hopefully there will be more retail activity and efforts to make Main Street  livelier will move forward.
