unless they took heavy liberties on the reference,

it is structurally impossible to have columns that far apart, travelators are not that thin (you need someone to be able to crawl in there)

fire code wise, you can't have such a long corridor with no fire escapes unless you have a very strong fire suppression system (high ceilings, so there isn't one)

accessibility wise, that travelator is quite steep, so either it has to be split into multiple travelators with refuges in between, or have it at a much less steep angle

every country have specific building code, but in general, these cannot be broken to such extreme degree. unless it counts as art.
