Bering Strait crossing crosses Diomede Islands
Likely route and expenses
Bridge option
If the crossing is chosen as a bridge, it would probably connect Wales, Alaska, to a location south of Uelen. The bridge would also likely be divided by the Diomede Islands, which are at the middle of the Bering Strait.
In 1994, Lin estimated the cost of a bridge to be "a few billion" dollars. The roads and railways on each side were estimated to cost $50 billion.  Lin contrasted this cost to petroleum resources "worth trillions". Discovery Channel's Extreme Engineering estimates the cost of a highway, electrified double-track high-speed rail, and pipelines at $105 billion (in 2007 US dollars), five times the original cost of the 1994 50-kilometer (31 mi) Channel Tunnel.
