A Bering land bridge still needs a usable supply route

What if a land bridge 25 kilometers wide formed between Alaska and Siberia in January 1942?

Its value depends on its location and connecting infrastructure: a northern crossing faces severe access problems, while a southern Aleutian route prompts a more favorable railway proposal.

A land bridge would still need connections to ports, roads and railways capable of carrying wartime supplies. Fleet argues that a crossing at the narrowest part of the Bering Strait would demand enormous construction efforts through remote terrain, while Soviet convoys across the northern Pacific already offer a supply route. Alex expects railway construction and an expanded Alaska Highway to attract support because they could reduce dependence on Arctic convoys. The argument changes when the bridge is understood to be 25 kilometers wide, without a specified length or northern alignment. A southern route following the Aleutians toward Kamchatka receives a much more favorable engineering assessment. Workforce requirements and construction risks remain disputed, and closing a sea passage also raises questions about ocean circulation.
