MIDTOWN: 42ND ST—65TH ST: Culminating with connections to Grand Central Station, the Midtown section is the most varied programmatically. The central median is transformed into a porous ground floor with small scale shops and galleries. Above, the new Park Avenue line connects the ground with a public third floor. This floor is dedicated to new offices and a reintroduction of the park. Single-loaded housing duplexes stack on top.
