The Bering Strait bridge is a theoretical structure over Bering straith connecting Cape Dezhnev in Chukotka, Russia and Cape Prince of Wales in Alaska, United States. This link would connect Asia, Africa and Europe with North and South America. This bridge could be spanned by a series of three bridges via the Diomede Islands, and would be long about 80 km (or 50 miles). Two of three bridges between islands would be longer than currently longest sea-crossing bridge in the world – Hangzhoy Bay Bridge. |
