Riverwalk Heights

Riverwalk Heights is a rental apartment building at 430 Main Street on Roosevelt Island, Manhattan, developed by Related Companies with the Hudson Companies. It is one of the newer towers of the Riverwalk development at the north end of the island’s Main Street, and part of its housing is set aside as workforce apartments for Memorial Sloan Kettering employees.

The building is steps from the East River promenade that rings the island, with Lighthouse Park and the Four Freedoms memorial at opposite ends. Riverwalk Park, Riverwalk Point and the other Riverwalk buildings are close by. The F stops at Roosevelt Island station, the Roosevelt Island Tramway runs to Second Avenue and 59th Street, and NYC Ferry stops at the island’s east-side landing.

Completed in 2024, the 30-story building holds 357 apartments and is one of the newest pieces of Southtown, the second phase of Roosevelt Island’s planned development. Its workforce housing for Memorial Sloan Kettering staff reflects the island’s long ties to medicine: for most of its history the island held hospitals, and several major Manhattan medical centers sit just across the East River.

Together the Riverwalk buildings give the island a cluster of newer rentals with modern amenities, in contrast to the older Mitchell-Lama and subsidized complexes of Northtown.
