Demolition preparations are underway at 77 West 66th Street, the site of a proposed supertall residential skyscraper on Manhattan’s Upper West Side. Developed by Extell, the structure could potentially stand 90 stories and 1,200 feet tall, making it the tallest building in the neighborhood by a significant margin. The site is bounded by West 67th Street to the north, West 66th Street to the south, and Columbus Avenue to the west.
