Bollards that can raise/lower aren’t that expensive and they don’t need to be mechanized. Back at my university, they’d raise them when they’d close off driveable areas for events and there’s just a hook to lift them up and secure at a higher height with a lock. They were made of solid metal and concrete so I assume they had some sort of counterweight underneath to help raise them.

They have them on every street leading into the busy part of Bourbon. This one was down for some reason.
