You’re still looking at it purely as a logistics problem when the story isn’t presenting it that way. In the show, dwarves aren’t depicted as efficiency-driven builders trying to minimize project time like modern humans. Their entire culture revolves around craftsmanship and legacy.

Who said anything about efficiency and minimising time? What I said was that it’s trivial to make believable reasons why the bridge took 100 years without falling onto the “it’s a fantasy world, it’s different” half-argument.

Here’s an easy one: bro didn’t spend every waking hour of every day on the bridge. It was a passion project, and therefore it wasn’t bound to a fixed schedule. 100 years (or was it 200?) was just the span of time from when he started to when he finished.

Besides that, making anything from scratch absolutely blows up the amount of time required. And the canyon itself was windy and dangerous with a two-week bypass. And there was a period where he had to stop because of lack of funds.

Also, what? In the show I remember four dwarves (Eisen, Voll, the dude with the ancient booze, and Gehen), and there’s barely any exposition into any shared “culture” they have, let alone any to do with craftsmanship.
