Hospital For Special Surgery’s Expansion Begins To Take Shape On Manhattan’s Upper East Side

Construction is underway on The Anna-Maria and Stephen Kellen Tower, a 12-story waterfront expansion of the Hospital For Special Surgery at 535 East 70th Street in the Lenox Hill section of Manhattan’s Upper East Side. Designed by EwingCole, the $200 million addition will span 100,000 square feet directly over FDR Drive and connect to the main hospital wing to the south via a sky bridge. Tishman Construction Corp. is the general contractor for the property, which is located between East 71st and 72nd Streets.

Recent photographs show the elevated platform comprised of large steel diagonal trusses, which will support the entirety of the new wing above the FDR Drive. Crews were seen welding within this superstructure, and we could likely see the first steel columns, girders, and beams for the main tower rise in the next couple of weeks. Temporary scaffolding is installed above the FDR Drive to protect vehicles from any falling debris, and to allow crews to work on the underside of the platform.
