hey slice that reminds me of something I saw back in the 90's. I'd forgotten about it.
One day I looked out my front window and up my street was a weird looking arch. I cant remember all the details of it now. It was only about semi-truck height. The weirdest thing i'd ever seen. i have never seen anything like this since.
I actually rang the weather bureau to ask if anything like this had been spotted and reported by others. But they said 'no'.
So i find your story fascinating
