A bridge 25 kilometers wide need not cross at the Bering Strait's narrowest point. A proposed curve through the Aleutian chain toward Kamchatka moves the railway to a different latitude and changes the engineering argument. Rail construction on that southern alignment is considered feasible, with permafrost and locomotive operation treated as manageable problems. Suggestions include double track, ballast and concrete or steel sleepers, while salt exposure and water entering wood receive particular attention. The remaining objection concerns the workforce and construction losses. Claims that this would be exceptionally lethal are challenged, so the feasibility assessment remains tied to the chosen route.

An Aleutian railway route changes the land-bridge calculation
A southern alignment changes the proposal from a remote northern approach into a railway whose track engineering is considered manageable.
