A bridge that hasn't moved since 1984 is no longer regulated as a moving bridge

The US Coast Guard removed a regulation for a drawbridge over the East River in Green Bay, Wisconsin. The bridge was replaced with a fixed structure in 1984, so the old rule was no longer needed.

This is a tiny administrative change, but it shows how old rules can linger for decades after the thing they regulate disappears. Every regulation adds a small amount of administrative overhead, even if it's just a line in a book. Removing obsolete rules clears out this kind of invisible clutter.
