The pin's event is the topping out, which New York YIMBY[3] and Connect CRE both reported on 24-25 October 2024 and which Wikipedia[2] gives as October 2024. The previous date of 1 June 2026 was Wikipedia's estimated completion date, not the topping out. No source gives the exact day, so this is dated to the last day of that month as an estimate.

Wikipedia states "as of 2025, construction is expected to be finished on June 1, 2026", an exact match to the pin's stored date, though this refers to overall project completion rather than the topping-out event named in the pin's title.

New York YIMBY reports 520 Fifth Avenue "was topped out" by October 2024, supporting the pin's title claim, though this predates the pin's stored 1 June 2026 date by about twenty months - that stored date appears to track the building's expected completion rather than its topping-out.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
