When will a Bering Strait crossing be completed?

A Bering Strait crossing is a hypothetical bridge and/or tunnel spanning the relatively narrow and shallow Bering Strait between the Chukotka Peninsula in Russia and the Seward Peninsula in the U.S. state of Alaska. The bridge/tunnel would provide a connection linking North America and Eurasia.

According to the dedicated Wikipedia page, various proposals have been made to build such a crossing:

According to a report in the Beijing Times in May 2014, Chinese transportation experts are proposing building a roughly 10,000 kilometer (6,213 mi)-long high-speed rail line from northeast China to the United States. The project would include a tunnel under the Bering Strait and connect to the contiguous United States via Canada.

Several American entrepreneurs have advanced private-sector proposals, such as an Alaska-based limited liability company founded in 2010 to lobby for a cross-straits connection and a 2018 cryptocurrency offering to fund the construction of a tunnel.

When will a Bering Strait crossing be completed


Resolution

This question resolves when any land link (a bridge or a tunnel) is created, and is carrying traffic before December 31st, 2035 (whether highly restricted traffic or open to the public).

This question resolves as >2040 if the project is not completed before 2040.

The type of traffic also doesn't matter. It could be motor vehicles, trains, a hyperloop, or pedestrian traffic, etc.

The exact location of the link also doesn't matter. For completeness sake, let's say:

  • It ultimately connects a part of mainland Alaska to a part of Mainland Russia
  • The link is contained within a distance of 500 miles of Little Diomede Island

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
