I would argue that most bridges made by engineers need some form of constant maintenance. I've seen bridge engineers in action and there was a thousand things to do for them, even long after the bridge was up. They ran around, improving the bridge, fixing things that was broke or inadequate. And as for a Bailey bridge: one small error in calculation and the bridge could break on the middle when heavy vehicles passed over, so someone better stay with the construction and operate it.
