The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
The saved calendar date is an estimated development-tracking target, not a verified exact opening. Status follows the quoted planning or actual-work milestone.
Construction research 2026-10-24: Marysville explicitly confirms actual AWS site-readiness activity at US33 Innovation Park.

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.
