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.

BioBioChile (a Chilean outlet) reports competing official estimates: the minister projecting the bridge "se entregaría en octubre de 2028" (October 2028) while the incoming minister suggests 2029-2030 given post-construction certification, bracketing the pin's stored June 2029 estimated date.
BNamericas, an English-language Latin American trade-press outlet, reports the Chacao Bridge's handover is expected in October 2028, corroborating the pin's existing reference from the Chilean public works ministry that the bridge is targeted for 2028.
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.
