Border Crossings Between United States and Russia

Separated by the narrow waters of the Bering Strait, Russia and the United States share a border that is closer than many expect. At its narrowest point, the two countries are just under 4 kilometers apart between the Diomede Islands. Despite this proximity, there are no official border crossings for travelers. Movement between the two nations requires flights or sea routes via other countries, as this maritime boundary has no functioning checkpoints.
