Construction Wank

The Transatlantic Bridge/Tunnel. Would never be built in reality because of the prohibitive startup costs compared to air and water transport, I think. But is it theoretically possible? The Mid-Atlantic Ridge would screw things up, for a start.

Harry Harrison had his characters build a reverse-suspension bridge over the main canyon on the Ridge. I think there were flexible sections with plans to someday lengthen the tunnel.

Considering you've got hundreds of atmospheres outside and vacuum inside the tunnel, one leak and-:eek:.

The TV show SeaQuest DSV had something like that around 1994, but it was only deep enough to allow shipping (8 atm?).

Anyway, I submit Frank Lloyd Wright's Mile High Illinois, a 5280-foot skyscraper set in Chicago. It was drawn in 1956.
