Check this massive thing out:
sagging traffic lights being lifted in a heavily-industrialized area near the Houston Ship Channel, I run into the very same process three quarters of a mile from my own house. At least one bucket truck was playing hopscotch with this load, jacking up the traffic lights in succession so that it could pass safely beneath each intersection it encountered.
It's weird how life is often like that - you don't see a phenomenon at all, right up until the point where you see it multiple unrelated times in rapid succession.
Anyway, I've no idea what that object is, or why it warranted such a complex haul through suburbia after dark on a Sunday night, but it sure must have been important to someone. My husband and I looked at this photo and thought, "Wouldn't it have been cheaper to dismantle it and re-erect it on site??" Apparently not.
