3rd Deepest Subway Stations: Roosevelt Island and Lexington Avenue/63rd Street, ~100 feet


While the long escalators at Lexington Avenue/63rd Street give the impression of going far, far below, this station and the one on Roosevelt Island, are not as steep as those in Upper Manhattan. They’re at about 100 feet below street level according to NYCSubway.org and Wiki). But if measured from sea level, Roosevelt Island’s is deeper than those in Upper Manhattan, according to this forum. The Lexington Avenue stop is also part of the Second Avenue Subway construction, and will feature four new subway entrances as part of the  Q line extension.
