Ahead of its yet-to-be-dated spring opening, things appear to be moving along at One World Observatory. Site signage at its West Street entrance spotted by a Curbed NY insider indicates only that the observation deck of 1WTC is "coming soon." Upon its opening, One World Observatory will become the highest observation deck in the northern hemisphere, and will look down upon its money-hemorrhaging WTC kingdom as well as the rest of New York City (and who knows what else).
UPDATE 4/7/15: An opening date has been announced.
