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 mid-2025 setback added cost and rework but the project team says it is still on schedule. Given as scheduled, per the source: "It is due to be completed in 2030."
Construction research 2026-10-24: FEDRO’s project site documents active second-tube excavation, including the May 2026 restart of TBM Paulina. The second tube targets opening in 2030, before renovation of the original tube. The second-tube budget is CHF 2.14 billion, ±15%, excluding VAT; it is not the cost of both tubes. Source quote: “CHF 2.14 billion has been earmarked for the construction of the second Gotthard tunnel[3] tube (estimate +/-15% excl. VAT).”

WebFetch could not retrieve Structurae's engineering-database page (403 Forbidden); its title, "Gotthard Road Tunnel - Second Tube (Göschenen/Airolo, 2030)," itself cites the same 2030 completion year as the pin's stored date, though unverified directly.
SwissInfo confirms "the tunnel should be excavated by 2027. It is due to be completed in 2030," directly matching the pin's stored end-of-2030 scheduled 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. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
