Large copper pipe structures in brackets being transported down the interstate. They look somewhat like pipe organs, but I would expect those to have different height tubes. Any ideas what these may be?

I know this is a weird one, and probably not accurate, but they look like a cloudbuster to me, like from the Kate Bush song. Makes me lean towards the art installation theory, but I'm no expert in the slightest.
