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.
A target, per the source: "no official date [is] set, although the broad expectation is for the early 2030s," with tunnel contracts expected to be awarded from 2030.
Engineering News-Record's own title - "Dubai Selects Teams for Key Contracts of $22B Sewer Tunnel Megaproject," published March 1, 2026 - is a respected construction trade publication consistent with the pin's dateConfidenceReasoning about contracts awarded from 2030, though the page itself returned a 403 error and could not be verified directly.[1]
WaterWorld's article describes construction expected to commence "as soon as 2019" over a six-year, two-phase build - a much more optimistic early timeline than the pin's current estimated 2032 completion date, indicating the project has since slipped substantially relative to this earlier projection.
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.
