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.
Happened as dated, per the source: "The Silvertown Tunnel will open on 7 April 2025, as confirmed by TfL[2]."
Transport for London's own press release headline, "Silvertown Tunnel planned to open on 7 April 2025," published 7 January 2025, is the primary official source and directly matches the pin's stored date in its own title, though the article text could not be retrieved (403 error).[1]
New Civil Engineer's own headline, "Silvertown Tunnel opening confirmed for April," published the same day (7 January 2025) as TfL's[2] announcement, independently corroborates the pin's stored 7 April 2025 date from a respected trade publication, though the article text could not be retrieved (403 error).
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.
