Believe it or not, Michael Bloomberg's last mayoral term ends in a year, and he's looking to leave behind something a bit more eye-catching than calorie counts and reasonably sized cups of soda. He's already overseen the steady skyward creep of One World Trade Center, green-lighted high-rise developments on the Williamsburg and Long Island City waterfronts, and pushed for a radical re-imagining of Hudson Yards in west Midtown. Now, he's proposed that a new class of mile-high skyscrapers be built in the area around Grand Central Terminal (between East 39th and East 57th Streets), reports the New York Times. Well, not quite mile-high, but the nineteen-story Roosevelt Hotel on Madison Avenue might be looking at a 39-floor growth spurt.
