Reply to comment by rubseb in Eli5 why do stairwells need to be have two flights in a spiral to go up one floor when escalators can just use the one flight going straight up for the same distance? by exmxn
Two flights of 10 steps are not significantly more expensive than one flight of 20 - all you're adding is the landing. Two escalators means twice the mechanical equipment.
