Kremlin envoy proposes 'Putin-Trump tunnel' to link Russia and US

Kinda a road to nowhere. On the US side there is a decent highway through Canada to the lower 48 but it is a hell of a drive and routes are constrained by crazy topography. In Siberia I think it is the same story.
A road tunnel would make much less sense.
Of course given current Russian belligerence this make no sense at the moment.
Now, in fairness, this wasn't actually Trump's idea, nor his ego that pushed it (so far).
