One Vanderbilt, the monstrous office tower being developed by SL Green and designed by Kohn Pederson Fox, will be New York City's second tallest building once it rises a block west of Grand Central Terminal. And with it will come $200 million of transit infrastructure improvements, provided by the developer, that were a condition of the Midtown East Rezoning (which is why the tower is allowed to be so tall in the first place) being approved. Today, the specifics of those improvements were released. The ones at One Vanderbilt will include a new subway entrance on 42nd Street, a new corridor and escalators connecting trains (the 4, 5, 6, 7, Shuttle, and Metro-North) to the under-construction LIRR East Side Access concourse, a 4,000 square-foot, ground-level indoor transit hall, and a public plaza between 42nd and 43rd Street on Vanderbilt.
There will also be a number of improvements made in and around Grand Central Terminal. These include a new stair in the basement of the Pershing Building connecting the IRT Lexington Avenue subway mezzanine to the platform, a new subway entrance at the southeast corner of East 42nd Street and Lexington Avenue, narrowing of stairs and columns in the station to provide more space, new stairs and an elevator for another subway entrance at East 42nd and Lex, a new mezzanine paid area in the basement of the Grand Hyatt Hotel with two new stairs to the subway platform, and the conversion of existing enclosed spaces into circulation areas.
The transit improvement are expected to be completed by 2020 or 2021, two years before the expected completion date of the East Side Access project.
UPDATE: Stantec is the firm leading the subway/transit design part of the project.
