The Diomede Islands lie directly in the middle of the Bering Strait.
Suggestions have been made for the construction of a bridge spanning the Bering Strait between Alaska and Siberia, dubbed by some the Intercontinental Peace Bridge, and, alternatively, for a connecting tunnel underneath the strait.
The BeringStrait is a sea strait between Cape Dezhnev, Russia, the easternmost point (169°43' W) of the Asian continent and Cape Prince of Wales, Alaska, the westernmost point (168°05' W) of the American continent, with latitude of about 65° 40' North, slightly south of the polar circle.
The strait is approximately 85 km (58 mi) wide, with a depth of 30–50 m (100–165 ft) and connects the Chukchi Sea (part of the Arctic Ocean) in the north with the Bering Sea (part of the Pacific Ocean) in the south.

The Bering land bridge, also known as Beringia, was a land bridge roughly 1,000 miles (1,600 km) north to south at its greatest extent, which joined present-day Alaska and eastern Siberia at various times during the Pleistocene ice ages.
The BeringStrait, the Chukchi Sea to the north and the Bering Sea to the south, are all shallow seas (map, right).
The Bering Land Bridge is significant for several reasons, not least because it enabled human migration to the Americas from Asia about 12,000 years ago (see Models of migration to the New World).
