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: "…enhagen rail travel to about 2.5 hours. Estimated date.…"
Femern A/S, the Danish state-owned company building the tunnel, publishes its own current construction status and schedule, an official primary source for the project's timeline.
Reports Sund & Baelt/Femern's[2] own statement that opening has slipped roughly two years past the pin's stored 2029 date, to no earlier than 2031, due to delays lowering the immersed tunnel segments; no single exact day has been set for the new target.
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.
