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.
Given as a target, not a fixed date, per the pin description: "…hi to Mumbai drive to roughly 12 hours. Estimated date.…"
Vahan Bazaar states the expressway is "targeted for full completion by November 2026", just a month ahead of the pin's stored 1 December 2026 estimated date.
Swarajya Mag reports the expressway is "largely on track for 2026 completion", with the Delhi-Vadodara section targeted for June 2026, but flags that three Gujarat packages "won't be ready until March 2028" - a caveat consistent with the pin's own 'Estimated date' framing around its stored 1 December 2026 date.
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.
